Wind noise is the structure, shape, dimensions, material, event and part simulation information included in building information (hoistway space information), shape, dimensions, material, event, transmission through various wall surfaces. It changes with the travel of the car according to the loss. The analysis unit 102c uses a wind noise calculation formula based on simulation conditions, BIM model building information, BIM parts part simulation information, and the like to generate wind noise in the hoistway as described above. Calculate In this case, the analysis unit 102c may individually calculate the wind noise in various places such as the wind noise in the car, the wind noise in the hoistway, the wind noise in the machine room, the wind sound in the adjacent living room, and the wind sound in the duct.

  Similarly, the analysis unit 102c determines the BIM model based on the input simulation conditions, the building information related to the building included in the target BIM model, and the BIM part included in the BIM information received by the information acquisition unit 102b. The simulation (noise simulation) regarding the noise generated when the elevator represented by the BIM part travels in the building represented by is executed. The analysis unit 102c executes a noise simulation using a calculation formula related to noise stored in the calculation formula file 106b. Various known calculation formulas may be used as the calculation formula for noise. In this case, the analysis unit 102c acquires, for example, simulation conditions, building information of the BIM model of the target building, and part information (part simulation information and the like) of the created BIM part. And the analysis part 102c performs the noise calculation which generate | occur | produces when the elevator which a BIM part travels in the building which a BIM model represents based on such information and the information memorize | stored in the calculation formula file 106b.

  For example, in an elevator, acoustic energy and sound pressure change according to the operating state of various devices, the lift position of the car, and the like. Noise is the structure, shape, dimensions, material, event and parts simulation information included in building information (hoistway space information), shape, dimensions, material, event, transmission loss of various wall surfaces. It changes with the traveling of the car according to the etc. The analysis unit 102c calculates the noise in the hoistway generated during the traveling of the elevator as described above using a calculation formula relating to noise based on the simulation conditions, the building information of the BIM model, the part simulation information of the BIM parts, and the like. To do. In this case, the analysis unit 102c may individually calculate noise in various places such as in-car noise, hoistway noise, machine room noise, adjacent room noise, and duct noise.

  Similarly, the analysis unit 102c determines the BIM model based on the input simulation conditions, the building information related to the building included in the target BIM model, and the BIM part included in the BIM information received by the information acquisition unit 102b. The simulation (vibration simulation) regarding the vibration generated when the elevator represented by the BIM part travels in the building represented by is executed. The analysis unit 102c executes a vibration simulation using a calculation formula relating to vibration stored in the calculation formula file 106b. Various known calculation formulas may be used as calculation formulas related to vibration. In this case, the analysis unit 102c acquires, for example, simulation conditions, building information of the BIM model of the target building, and part information (part simulation information and the like) of the created BIM part. And the analysis part 102c performs the vibration calculation which generate | occur | produces at the time of the driving | running | working of the elevator which a BIM part represents based on such information and the information memorize | stored in the calculation formula file 106b.

  For example, in an elevator, the vibration energy changes according to the operating state of various devices, the lift position of the car, and the like. Vibration is the structure, shape, dimensions, material, event and parts simulation information included in the building information (hoistway space information), shape, dimensions, material, event, transmission loss of various wall surfaces. It changes with the traveling of the car according to the etc. The analysis unit 102c calculates the vibration in the hoistway generated during the traveling of the elevator as described above using a calculation formula relating to vibration based on the simulation condition, the building information of the BIM model, the part simulation information of the BIM part, and the like. To do. In this case, the analysis unit 102c may individually calculate vibrations in various places such as in-car vibrations, hoistway vibrations, machine room vibrations, adjacent living room vibrations, and duct internal vibrations.

  Here, details of the vibration / noise prediction method using the BIM used in the present embodiment will be described. In addition, the vibration / noise prediction method shown below is an example, and is not limited to the following.

  Conventionally, when building interior noise or vibration problems occur due to vibrations (noise) caused by elevators, information on the vibration characteristics of the building side is often unclear, and problems are often found after actual start of driving. It was mainstream to follow up the countermeasures. At this time, information on the element arrangement on the building side (for example, the positional relationship between the room position and the vibration / noise source, propagation path, etc.) may not be clear at the time of planning, and it is difficult to predict at the initial stage. Met. In addition, even if there is a building structure (for example, information such as beam position and size), there may be a propagation path that cannot be determined only by the information presented in the elevator plan. It was. Furthermore, when there is information on the building side in advance and an elevator plan is made, it is necessary to model and analyze each piece of information on the elevator plan side, which is a factor that degrades time efficiency.

  Therefore, in this embodiment, the sharing of information and bidirectionalization, which are the features of BIM, are used, and in the main model, the data on the elevator side is embedded in the data on the building side to extract the necessary information and the analysis work is performed. doing. Thereby, according to this embodiment, an efficient design can be performed by identifying a problem in a planning stage and taking a countermeasure.

  Specifically, in the present embodiment, a database in which various additional data is added in addition to the steel beam and wall data (model) held as BIM data is configured. The configuration data includes mass, length, cross-sectional dimensions, center of gravity, natural frequency, etc., and also the connection status (eg, rigid body connection or displacement limitation) with adjacent beams / walls. More specifically, in addition to the configuration data of the BIM model, coupling information (degree of freedom information) between the models (particularly the structure-related model) and parameters related to vibration / noise are added. As BIM software, it is desirable to have a pre-post function in order to cooperate with an external solver. This is so that the analysis result can be confirmed on the BIM software. In addition, necessary data (for example, model shape (node position, etc.), element information (shape, thickness, etc.), material properties (Young's modulus, etc.), boundary conditions (load, position of restraint, direction, etc.)) to the external solver Provide a function to transfer (intermediate file, etc.). The pre-post function may be provided in the BIM software itself, but it is desirable that the result can be reflected in the BIM software.

  These data can be arbitrarily output from the BIM model, and can be transferred to analysis software. There are various data formats, but conversion to an intermediate file format or the like is also possible if necessary. Based on the transferred data, an effect of simplifying modeling and setting of coupling conditions for various analyzes is obtained. Specifically, the pre-post function is used to visually confirm and set information to be sent to an analysis solver (for example, NEi Nastran), and to reflect and confirm the result from the solver on the BIM model. Also, by having various analysis data on the BIM software, a series of design work and the result can be confirmed on the BIM software.

  As a result, it is possible to shorten the time required for modeling during analysis, installation of constraint conditions, and the like, and the time efficiency required for the entire structure and partial analysis work can be increased. In addition, by creating a model with BIM software, extracting the part you want to perform structural analysis from it, executing the analysis and confirming the result, you can carry out more detailed examination and confirmation, information for each equipment part It becomes possible to grasp the problem by sharing. In addition to the data necessary for vibration analysis, it can be applied to noise analysis by converting the data of various wall materials and individual transmission losses into data.

  As described above, the vibration / noise prediction method of the present embodiment is not limited to the shape, spatial relationship, geographic information, quantity, and building element properties (for example, mass, cross-sectional specifications) in the BIM model. (Particularly structure-related models) information (degree-of-freedom information) and parameters related to vibration and noise (frequency, sound pressure level of generated sound, etc.) are given, and the whole or part of the structure analysis as necessary Generate a model so that it can be passed to an external solver. Further, it is desirable that the vibration / noise prediction method of the present embodiment pulls back the result of the analysis performed by the external solver so that the result can be displayed on the BIM.

  Therefore, according to the vibration / noise prediction method of the present embodiment, the database has various data on the vibration mode eigenvalues, cross-sectional specifications, and connection states (whether rigid connection or not) related to the building beams, and the data as necessary. Can be extracted with analysis software (or an intermediate file is discharged) and various analyzes can be performed. In addition, it becomes possible to predict the propagation path of vibration by clarifying the connection status of each building beam. In addition, not only building beams but also the wall thickness, mass (material), transmission loss amount are made into a database, and by setting the sound source at a specific coordinate position on the building data (model) (directivity and sound pressure level), It is possible to calculate the distance from the sound source position to each wall, etc., and to perform noise prediction considering transmission loss.

  Hereinafter, the description of the folding unit 102c will be continued.

  The analysis unit 102c typically represents a BIM model based on input simulation conditions (for example, simulation conditions related to elevator swing) and building information related to a building included in the target BIM model. Analyzes the shaking of the building when an external force is applied to the building (swing simulation). The analysis unit 102c executes a building shake analysis using a calculation formula relating to the building shake stored in the calculation formula file 106b. For example, various known calculation formulas based on a vibration equation or the like may be used as the calculation formula regarding the shaking of the building. The calculation formula is, for example, “Explanation of Elevator Technical Standard 2009 Edition (Elevator Seismic Design / Construction Guidelines), Elevator / Rope Lateral Vibration Analysis (Journal of the Japan Society of Mechanical Engineers (C) 77, 773 (2011-1)) May be used. In this case, the analysis unit 102c, for example, the type and size of the assumed external force to be applied to the building included in the simulation condition, the building height, the number of floors included in the building information of the BIM model of the target building, Get the floor height, structure type, dimensions of each part, building shape, mass (weight) of each floor, spring constant (rigidity) of each floor, quantity and characteristics of building members, member strength, etc. And the analysis part 102c performs the analysis calculation regarding the shake of the said building when external force acts on the building which a BIM model represents based on such information and the information memorize | stored in the calculation formula file 106b. The analysis result of the shaking of the building analyzed by the analyzing unit 102c is, for example, at least one of the natural frequency of the building, the shaking width of each part, acceleration, vibration mode, vibration behavior, shaking process (transition process), and the like. May be included.

  And furthermore, the analysis part 102c is based on the analysis result of the analyzed shaking of the building, the simulation condition regarding the swing of the elevator that is input, and the BIM part included in the BIM information received by the information acquisition part 102b. Analyzes the swing of the elevator represented by the BIM part when an external force is applied to the building represented by the BIM model (swing simulation). The analysis unit 102c performs the swing analysis of the elevator using the calculation formula relating to the swing of the elevator stored in the calculation formula file 106b. For example, various known calculation formulas based on a vibration equation or the like may be used as the calculation formula regarding the swing of the elevator. In this case, the analysis unit 102c, for example, the natural frequency of the building included in the building vibration analysis result, the swing width of each unit, the vibration mode, the vibration behavior, the load on the elevator included in the simulation conditions, the BIM part Elevator lifting process, lifting speed, hoistway layout, elevator material, diameter (thickness), weight, hitch shape, number, tension / load, roping method Get the number of sheaves. And the analysis part 102c performs analysis calculation regarding the shaking of the elevator represented by the BIM part when an external force is applied to the building represented by the BIM model based on the information stored in the calculation formula file 106b. The analysis result of the elevator swing analyzed by the analysis unit 102c may include at least one of swing width, acceleration, vibration mode, vibration behavior, swing process (transition process), and the like. Note that the analysis unit 102c is not limited to the swing of the long object while the elevator is traveling when an external force is applied to the building, but is also about the swing of the elevator that is stopped when the external force is applied to the building. You may analyze.

  For example, an elevator as an elevator is vibrated by a shaking of a building during a strong wind or an earthquake. The amount of shaking of the elevator varies depending on the magnitude of shaking of the building and the acceleration of the building when an external force is applied to the building. In addition, the swinging of the elevator is, for example, the lifting process, the lifting speed, the hoistway layout, the material of the elevating object, the diameter (thickness), the weight, the hitch shape, the number, the tension / load, the roping method, the number of sheaves It also changes depending on. The analysis unit 102c uses a calculation formula related to the swing of the elevator based on the analysis result of the analyzed swing of the building, the input simulation conditions, the part simulation information of the BIM part received by the information acquisition unit 102b, and the like. And calculate the swing of the elevator as described above.

  The analysis unit 102c is based on the simulation conditions regarding the input elevator, the building information regarding the building included in the BIM model stored in the BIM model database 106a, and the BIM parts changed by the changing unit 102g described later. Then, various simulations related to the elevator described above may be executed.

  In addition, the countermeasure application unit 102d acquires, by the information acquisition unit 102b, a BIM part including a countermeasure for the simulation result based on the results of various simulations related to wind noise, noise, vibration, and vibration executed by the analysis unit 102c. It is a countermeasure application means created using the part information stored in the part information database 206a.

The countermeasure application unit 102d determines that any one of the wind noise in the car, the wind noise in the hoistway, the wind sound in the machine room, the wind sound in the adjacent living room, and the wind sound in the duct exceeds the respective wind sound allowable values. Alternatively, the BIM part may be created as described above, or the BIM part may be created as described above when all the wind sounds exceed the wind sound allowable value. Here, the wind noise allowable value is a value corresponding to the designated value of the wind sound allowable value included in the simulation condition as described above.

Created using the part information stored in the database 206a. In this case, when the noise generated when the elevator represented by the BIM part exceeds the preset noise allowable value based on the result of the noise simulation executed by the analysis unit 102c, the countermeasure application unit 102d A BIM part including a noise countermeasure that is less than or equal to the allowable noise value is created using the part information stored in the part information database 206a acquired by the information acquisition unit 102b.

It also functions as an integrated modeling means for creating an integrated BIM model incorporated in the BIM model of the building stored in the BIM model database 106a. For example, the screen generation unit 102e creates a three-dimensional integrated BIM model in which elevator BIM parts as shown in FIG. 4 are incorporated into a building BIM model. Here, FIG. 4 is a diagram illustrating an example of an integrated BIM model in which BIM parts are incorporated into the BIM model.

The screen generation unit 102e may store the created integrated BIM model in the storage unit 106 and construct an integrated BIM model database (not shown). Then, the screen generation unit 102e generates a layout screen including the created integrated BIM model.

  Further, the screen generation unit 102e according to the present embodiment, together with the created integrated BIM model, is executed by the analysis unit 102c as illustrated in FIG. 5 or FIG. 6 and transmitted from the server device 200, for example.

A space at a wind sound level that is yellow as the “attention level” and sufficiently low relative to the wind sound allowable value is displayed as a “no problem level” in white (or blue) and displayed on the display unit 114 in different colors.

In FIG. 7, a BIM part before wind noise countermeasure and a car plan view showing the BIM part in two dimensions are displayed on the left side, and a BIM part after wind noise countermeasure and the BIM part are displayed in two dimensions on the right side. The car floor plan is displayed.

  In FIG. 7, the load capacity of the elevator shown by the BIM parts before wind noise countermeasures shown on the left side in FIG. 7 and the load capacity of the elevator shown by the BIM parts after wind noise countermeasures shown on the right side in FIG. The same. The difference between the two is the hoistway plane dimensions, the overhead dimensions, and the wind-tuning capsule of the car. In FIG. 7, for example, when the size of the hoistway of the BIM part shown on the left side in FIG. 7 is changed to a small value by the changing unit 102g described later, the countermeasure application unit 102d adds the car represented by the BIM part shown on the right side in FIG. A wind-control capsule is added as a measure against wind noise. In addition, as shown on the right side in FIG. 7, the countermeasure application unit 102d automatically expands the hoistway top dimension by the amount of the upper dimension increased by the wind conditioned capsule added to the car represented by the BIM part. When the BIM parts car shown on the right side in FIG. 7 needs to be sealed around the door, the countermeasure application unit 102d automatically changes the structure to that with packing as a countermeasure against wind noise.

  As described above, in the present embodiment, based on the result of the wind noise simulation executed by the analysis unit 102c, the countermeasure application unit 102d automatically changes all relevant parts as a wind noise countermeasure. Further, in the present embodiment, the wind noise countermeasure level may be determined by the analyzing unit 102c from the elevator car size, the car speed parameter, the hoistway dimensions in which the car is arranged, and the like. Then, the countermeasure application unit 102d may feed back the wind noise countermeasure to the elevator car itself or another device such as a door, and automatically change the shape of the BIM part of the elevator as a wind noise countermeasure. At this time, the wind noise countermeasure level may be determined for a plurality of elevators in conjunction with the number of elevators in the bank.

  More specifically, in the present embodiment, the analysis unit 102c determines necessary wind noise countermeasures associated with changes in the dimensions of the elevator hoistway. Further, the countermeasure application unit 102d changes the shape of the car (for example, the presence / absence of a wind conditioned capsule, the necessity of double side plates, the apron shape, the apron width, etc.) as a wind noise countermeasure. In addition, the countermeasure application unit 102d changes the shape of the holder (for example, duplexing of the holder, whether or not there is a gap blocking around the door) and the hole fisher plate (for example, the shape and width dimension). Furthermore, the countermeasure application unit 102d changes the hoistway shape to reflect the hoistway plane dimensions, overhead dimensions, and pit dimensions that are required in accordance with these changes. In this embodiment, the elevator car has a speed parameter. In this case, the analysis unit 102c determines a necessary wind noise countermeasure accompanying the change of the speed parameter. Similarly, the countermeasure application unit 102d changes the shape of the car, changes the shape of the hold door, changes the hole fisher plate, and the hoistway plane dimensions and overhead required for these changes as countermeasures against wind noise. Change the hoistway shape to reflect the dimensions and pit dimensions. Further, in this embodiment, the analysis unit 102c determines the wind noise countermeasure level for a plurality of elevators in conjunction with the number of elevators in the bank. In this case, the countermeasure application unit 102d similarly changes the shape of the car, changes the shape of the hold door, changes the hole fisher plate, and the hoistway plane dimensions required for these changes as wind noise countermeasures. The hoistway shape is changed to reflect the overhead dimensions and pit dimensions. In the present embodiment, the screen display unit 102f changes and displays the color of the wind noise countermeasure application location. In the present embodiment, the content of the wind noise countermeasure may be written in characters so that the user can easily understand what the wind noise countermeasure is applied to by the screen display unit 102f.

  Therefore, according to the present embodiment, since the wind noise countermeasure can be automatically determined and reflected in the layout drawing, a correction error can be corrected when the wind noise countermeasure is applied to the user as compared with the conventional wind noise countermeasure method. There is an advantage that it is difficult to generate. Here, conventionally, referring to the manual, wind noise countermeasures were selected based on the number of elevators in the bank and the rated speed, and what is reflected in the layout drawing as each wind noise countermeasure based on the selection result, I started drawing after confirming the required dimensions. On the other hand, according to the present embodiment, for example, wind noise countermeasures suitable for the hoistway are automatically determined based on the vertical and horizontal hoistway spaces, elevator speeds, loading and number of units, and the car air conditioner plate, air conditioner capsule, door BIM parts including wind noise countermeasures such as bag dooring and gap countermeasures can be created. Further, according to the present embodiment, when the wind noise countermeasure rank is changed when the hoistway dimensions are changed, an appropriate wind noise countermeasure can be automatically applied to the BIM part to be changed. . Further, according to the present embodiment, when the overhead dimension or the pit dimension is insufficient, the hoistway dimension can be automatically enlarged to display the shortage.

  The screen display unit 102f is executed by the analysis unit 102c in a state where the elevator represented by the BIM part including the noise countermeasure and / or the vibration countermeasure created by the countermeasure application unit 102d is incorporated in the building represented by the BIM model. The result of the noise simulation and / or vibration simulation is displayed on the display unit 114. For example, the screen display unit 102f causes the display unit 114 to display BIM parts including noise countermeasures and / or vibration countermeasures, as shown in FIG. FIG. 8 is a diagram illustrating an example of a BIM part including noise (vibration) countermeasures. In FIG. 8, BIM parts before noise (vibration) countermeasures and noise simulation results before noise (vibration) countermeasures are displayed on the left side, and BIM parts and noise (vibration) countermeasures after noise (vibration) countermeasures are displayed on the right side. The result of later noise simulation is displayed.

  In FIG. 8, the BIM parts before noise (vibration) countermeasures shown on the left side in FIG. 8 indicate the machine room portion of the elevator. The BIM part after noise (vibration) countermeasures shown on the right side in FIG. 8 shows a state in which a sound absorbing material and cinder concrete as noise (vibration) countermeasures are applied to the machine room portion of the elevator. In other words, the BIM part shown on the right side in FIG. 8 is one in which an optimum noise (vibration) countermeasure is applied to the BIM part shown on the left side in FIG. 8 by the countermeasure application unit 102d. Accordingly, when the noise simulation result shown on the left side in FIG. 8 and the noise simulation result shown on the right side in FIG. 8 are compared, in the BIM part after the noise (vibration) countermeasure shown on the right side in FIG. The noise level is low.

  As described above, in this embodiment, the analysis unit 102c can know the noise and noise in the building by inputting parameters using the design support tool (hereinafter referred to as BIM), and the countermeasure application unit 102d The optimum noise countermeasure can be automatically proposed. Noise countermeasures include, for example, countermeasures to elevator draft noise, changes to whisper chains, and attachment of sound absorbing materials to building-side machine rooms and hoistways such as conductor cover attachment. In this embodiment, the countermeasure application unit 102d automatically proposes noise countermeasures for elevators and noise countermeasures for buildings. As a result, the optimal noise countermeasure level can be proposed by presenting numerical values such as the expected draft sound to the customer, so it is possible to reduce excessive noise proposals and problems related to noise and vibration after delivery. It becomes.

  More specifically, in this embodiment, in a three-dimensional building model created using BIM, parameters such as car speed and hoistway dimensions are input, and the noise in the building is confirmed numerically. The level of elevator noise countermeasures and building noise countermeasures are automatically calculated. Thereby, optimization of noise countermeasures for the elevator and noise countermeasures for the building (for example, attachment of a sound absorbing material) can be proposed. In addition, in this embodiment, it is possible to present the elevator specifications to the customer while visualizing and displaying the noise. In addition, noise in the entire building can be examined by including information on the building side. In addition, it is possible to present the state of noise in various places by numerical values. It is also possible to propose optimal zoning and elevator arrangement for noise countermeasures. In the present embodiment, noise visualization may be displayed by color, contour lines, or the like. Further, the noise source of noise and the importance level of the noise source may be displayed.

  Therefore, according to the present embodiment, noise countermeasures can be automatically determined and reflected in the layout, so that there is an advantage that the optimum noise countermeasures can be efficiently examined as compared with the conventional noise countermeasure methods. is there. Here, conventionally, for each property in the architectural drawing, the person in charge determines the wind noise countermeasure level based on the number of units in the same hoistway and the elevator speed, and makes a wind vent hole above and below the hoistway by noise prediction, Sound absorbing material was affixed to the hoistway and machine room. In this conventional method, since experience values are also taken into account, there are cases where the specification becomes excessive or the optimality of the demand on the building side cannot be determined. On the other hand, according to the present embodiment, in a three-dimensional building model created using BIM, parameters such as car speed and hoistway dimensions are input, and the noise in the building is checked numerically to obtain the optimum elevator noise. It is possible to automatically calculate the level of countermeasures and noise countermeasures on the building side. As a result, by automatically taking noise countermeasures, workability and accuracy can be improved, efficient countermeasures can be studied, and customer troubles can be reduced.

  Specifically, in this embodiment, BIM is used, the influence on the elevator by building vibration (building vibration due to earthquake and wind pressure) is automatically calculated by parameter input, and the result is visualized in three dimensions. Thus, according to the present embodiment, automatic processing is performed according to related parameters such as the natural period of the ground (dominant frequency), the seismic response analysis result / floor response of the building, the natural period of the elevator / seismic data, and the data indicating the past example of the elevator. By calculating the seismic strength of the elevator, the affected parts can be color-coded and judged visually.
