Description

  The present invention relates to a running test apparatus for railway vehicles, and is particularly suitable for a running test apparatus for railway vehicles that simulates running equivalent to main line running by rotating a rail wheel corresponding to a rail of a railway vehicle.

  With the increase in speed and weight of railway vehicles, relatively high-frequency vibrations are likely to be generated in the bogie, which tends to increase the level of vibration and noise when transmitted to the car body. In order to improve such a situation, it is desired to elucidate vibrations and noise generation of railway vehicles and their transmission mechanisms and to establish a technique for reducing them. In addition, with the rapid increase in speed of railway vehicles, improving the performance of railway vehicles and operating safety are important issues. As one means for elucidating and improving these problems, a running test apparatus for railway vehicles that faithfully reproduces and simulates rail running is used.

  A conventional railcar running test apparatus includes a rail wheel corresponding to a rail, a rail motor for rotating the rail wheel to simulate a run equivalent to the rail run, and up and down, left and right when the run is simulated. The rail wheel hydraulic exciter and hydraulic system for simulating the dynamic change of the trajectory at any frequency and arbitrary waveform type (displacement, single sine wave), and equivalent mass equivalent to the actual vehicle And a flywheel device for adjustment.

  In addition, as a patent document regarding a running test apparatus for a railway vehicle, for example, Japanese Patent Laid-Open No. 5-289696 (Patent Document 1) is cited.

JP-A-5-289696

  However, in the conventional running test apparatus for railway vehicles, the vibration simulation waveform has a low frequency of approximately 25 Hz or less, and therefore vibration data measured by an actual vehicle, or track data obtained by track inspection and ground measurement, Equivalent continuous driving is not possible. Moreover, the vibration data to be simulated is reproduction of ground data, that is, displacement data, and vibration of high-frequency acceleration data generated in each device of the railway vehicle cannot be reproduced.

  In order to simulate running on the main line, the vehicle speed and vibration data at an arbitrary point need to match, but in a conventional railway vehicle running test device, the rail wheel motor and the equipment mounted on the rail vehicle operate in conjunction with each other. Therefore, it is difficult to match the traveling speed and vibration data at an arbitrary point.

  Further, when arbitrary vibration waveform data is output at a predetermined distance interval (for example, 1 m interval), the conventional railway vehicle traveling test apparatus outputs the vibration waveform data by changing the vehicle traveling speed of continuous traveling operation. The interval varies (a phenomenon in which the sampling interval varies), and the displacement data of the output vibration waveform data has a waveform shape such as a rectangular wave. As a result, a phenomenon in which sudden unevenness occurs in vibration simulation may occur, and it may be difficult to perform continuous running operation equivalent to that of an actual vehicle. Furthermore, in the conventional railway vehicle running test apparatus, there is a concern that the continuous running operation equivalent to that of an actual vehicle becomes difficult due to the problem that the acceleration state cannot be maintained in the reproduction of acceleration vibration data.

  In addition, in the conventional railcar running test device, there is no running controller control device that controls driving and braking devices by railcar-equipped equipment or confirms the state of equipment under continuous running operation. Under the test conditions that reproduce the vibration of the time, it is impossible to simulate the actual condition of the disk bolt or disk by simulating the actual vehicle, and it is difficult to grasp in detail the confirmation of the process just before the failure.

  In general, it is very inefficient in terms of cost, personnel, and time to perform a driving test using the main line in investigation and confirmation work such as driving characteristics, and it is difficult to set test conditions for safety. There is a case. In addition, even in the main line running simulation of only arbitrary waveform types (displacement amount, single sine wave), the number of tests for each condition increases, which is very inefficient in terms of cost, personnel, and time.

  The object of the present invention is to faithfully reproduce and simulate rail running to grasp the dynamic behavior and performance evaluation of railway vehicle mounted equipment during actual vehicle running in a short period and at low cost under various vibration environments.

  By IP network management, it is possible to immediately transfer the track data from track inspection and ground measurement to the railroad vehicle running test device 50, which simulates ground changes on the main line to ensure the safety of railcar operation. It becomes possible to confirm.

  The operation of each device in the continuous running operation will be described with reference to FIG. FIG. 5 is a diagram showing an operation flow of the running test apparatus 50 for rail vehicles. It is assumed that the railway vehicle 70 as a specimen is mounted on the railway vehicle running test apparatus 50.

  First, in the panel power-on step 5-1, the high-voltage panel power of the high-voltage power receiving panel 24, the transformer panel 25, and the motor control panel 26 is turned on, and the railway vehicle running test apparatus 50 is set in a power receiving state.

  Next, in the control power on processing step 5-2, the control system power is turned on from the central operation panel 28, and the vibration control device 29, the travel controller control device 30, the measurement system, and the monitoring recording subsystem travel for the railway vehicle. Launch the test equipment application.

  Next, continuous driving operation conditions are set in operation preparation processing step 5-3. For example, the driving conditions and vibration conditions for the rail wheel 16 and the control conditions for the railway vehicle equipment are set. Also, flywheel setting for adjusting equivalent mass, run curve setting according to kilometer based on running record such as ATC chart, vibration data measured by actual vehicle, or track data by track inspection vehicle and ground measurement A vibration waveform for outputting an arbitrary vibration waveform at a specified distance interval is set using vehicle vibration data or track data processed by a PC or the like.

  Next, in the system startup processing step 5-4, the pre-continuous driving operation processing is performed. Specifically, a lubricating device, a hydraulic power source system, and a pump such as a cleaning pump are started from the central operation panel 28. Further, the temperature and pressure of the hydraulic pressure are adjusted, and the rail wheel vertical hydraulic exciter 13 is moved to a designated position to take an initial state in which the driving operation can be performed.

  Next, in operation processing step 5-5, the central operation panel 28 instructs the vibration control device 29, the travel controller control device 30, the measurement system, and the monitoring and recording subsystem to start operation, and the disc brake of the rail wheel 16 is discriminated. Is released. Then, the vibration control device 29 automatically outputs the trajectory data obtained by the predetermined trajectory inspection vehicle and the ground measurement as waveform data in kilometer units, and directly controls the electrohydraulic servovalve for hydraulic vibration excitation. The machines 13 and 14 are driven to vibrate the rail wheel 16. The travel controller control device 30 rotates the rail wheel 16 based on the run curve setting corresponding to the kilometer based on a travel record such as a preset ATC chart.

  The operation of the travel controller control device 30 in the driving process step 5-5 will be described more specifically.

  The travel controller control device 30 operates according to a run curve condition corresponding to a travel distance in accordance with a travel performance record such as a control condition of an on-railway vehicle-equipped device, an ATC chart, or the like set in advance for driving preparation. For example, in the case of continuous running operation from Tokyo Station to Shin-Yokohama Station, a power running notch and brake notch signal in a running record such as an ATC chart from the Tokyo station point is acquired, and the control device of the railway vehicle mounted device is controlled. Further, the travel speed and travel distance of the railway vehicle 70 are measured in real time from the rotational speed of the rail wheel 16 at that time.

  Similarly, load resistance is applied to the rail wheel 16 on the basis of the previously calculated route data, for example, gradient, curve, tunnel, and travel resistance based on the calculated travel speed and travel distance. Simulate. In this running resistance, it is possible to share the brake load according to the brake load ratio between the cars in the train. That is, it is possible to simulate running of an actual vehicle by applying a running resistance that becomes a load (torque) in a direction opposite to the wheel rotation of the railway vehicle.

  In addition, other vehicle power failure simulation detection signal, sliding detection simulation signal, etc. are added in the traveling record such as ATC chart, and when the vehicle passes through the specified traveling distance position, the traveling controller control device becomes the railroad vehicle equipment control device. It is possible to simulate a command (event). Not only the continuous driving operation from Tokyo Station to Shin-Yokohama Station, it is also possible to simulate any station section such as Tokyo to Nagoya, Nagoya to Tokyo, Tokyo to Hakata.

  In parallel with the processing by the travel controller control device 30, the vibration control device 29 reproduces the vibration. The vibration control device 29 is based on the trajectory data obtained by the track inspection and ground measurement and the vehicle vibration data and the trajectory data processed by the PC or the like set in advance in preparation for driving. The left and right hydraulic exciter 14, the bogie vertical hydraulic exciter 34, the bogie left and right hydraulic exciter 35, and the vehicle body hydraulic exciter 36 are dynamically driven to change the trajectory, the height error, the bogie, and the railway including the car body. Reproduce the vibration of each part of the vehicle.

In order to faithfully simulate the travel of the main line, it is necessary to output vibration data for the travel distance of the railway vehicle. FIG. 8 schematically shows a chart of the distance traveled from the Tokyo station of the railway vehicle by 1 meter intervals. 8, waveform 8-1 shows the running speed of the rotational speed, or railcar rail wheels for travel distance, the waveform 8-2 shows the vibration data with respect to the travel distance position of 1m intervals. This vibration data is a displacement value or an acceleration value obtained by measurement by a track inspection vehicle or the like.

  The linear chart linear interpolation will be described with reference to FIGS. FIG. 6 is a block diagram of a control system that performs kilometer chart linear interpolation, and FIG. 7 is a flowchart of kilometer chart linear interpolation.

  As shown in FIG. 6, the control system that performs linear chart linear interpolation includes vibration data reading means 37, storage means 38, numerical value calculating means 39, numerical value calculating means 40 having real-time properties, pulse counting means 41, and excitation. Machine control means 42 is provided.

When tested by flow chart shown in FIG. 7 is started, reading a chart c1 vibration data reading means 37 kilometrage in step S11, the storage unit 38 in step S12 stores the chart c1 kilometrage. In step S13, the numerical value calculation means 39 arbitrarily shapes the kilometer chart c1 stored in the storage means 38. In step S14, the storage unit 38 stores the kilometer chart c2 arbitrarily shaped by the numerical value calculation unit 39.

  In step S15, based on the pulse count c3 acquired by the pulse count means 41, the numerical calculation means 40 having real-time characteristics calculates the travel distance. In step 16, linear interpolation is performed based on the kilometer chart with respect to the travel distance calculated by the numerical value calculation means 40, and the command signal c4 is calculated. In step S17, the calculated command signal c4 is output from the numerical calculation means 40 to the vibration means. In step S18, on the basis of the command signal c4, the rail wheel vertical hydraulic shaker 13, the rail wheel horizontal hydraulic shaker 14, the cart vertical hydraulic shaker 34, the cart left and right hydraulic shaker 35, and the vehicle body hydraulic shaker 36 is driven. In step S19, an end determination is made. If not, step S15 to step S19 are repeated.

  In order to faithfully simulate main line travel, it is necessary to execute steps S15 to S19 within an arbitrary time. For this purpose, numerical calculation means 39 for shaping a kilometer chart and numerical calculation means 40 having a real-time property for performing a task requiring real-time property are used.

  FIG. 9 is an enlarged view of kilometer chart vibration data. In FIG. 9, a waveform 9-2 is an output signal when interpolation is not performed, and a waveform 9-3 is an output signal when interpolation is performed. A smooth output signal can also be output by filtering the waveform 9-3.

  The kilometer chart vibration data is a displacement value or an acceleration value. However, when the acceleration vibration waveform is simulated, the acceleration value of the vibration data at the designated travel distance position of 1 m intervals can be considered in the same manner as the waveform 8-2. However, in order to actually keep the acceleration constant, the vibrator must continue to operate in the direction of acceleration. Therefore, in the waveform 9-2 when the interpolation is not performed, there is a possibility that it is difficult to reproduce the acceleration value with respect to the designated travel distance position in about a kilometer. On the other hand, in the present embodiment, the vibration of the acceleration value is simulated by using the waveform 9-3 that is linearly interpolated even if the vibration data is 1 m apart without increasing the data amount with a minute interval. can do.

  In the description related to FIG. 9 described above, the linear interpolation method is described. However, the interpolation method may be spline interpolation or curve interpolation by Lagrangian processing.

  Next, the description will be limited to the vibration reproduction shown in FIG.

  Track data from track inspection and ground measurement, vehicle vibration data and track data processed by PC, etc. are converted into displacement, acceleration and load data, and each rail wheel vertical hydraulic shaker, rail wheel left and right hydraulic shaker The target waveform 11-1 for the bogie vertical hydraulic exciter, the cart left and right hydraulic exciter, and the vehicle body hydraulic exciter is created.

  The created target waveform is sent to the vibration control device of the running test apparatus for railway vehicles via the IP network 11-2, and can be made into a database. The electrohydraulic servovalve can be directly controlled by the device to drive the hydraulic exciter, so that vibration can be applied to the railway vehicle as a specimen.

  However, the target waveform may not match the response waveform from the measurement of vibration acceleration, displacement, etc. attached to the railway vehicle due to the reaction force from the railway vehicle as the specimen, the electrohydraulic servo valve, and the characteristics of the oil. In other words, since the transfer characteristic of the response waveform to the target waveform may deteriorate, the inverse transfer function data of the transfer function is used as compensation data, and the target waveform is added as a compensation value so that the target waveform matches the response waveform. There is provided a function of performing the reproduction process 11-3, and automatically shaping 11-4 a new target waveform that can be reproduced by shaping and processing the target waveform. Each controller of the vibration control device, the travel controller control device, the measurement system, and the monitoring and recording subsystem is connected with a dedicated control network through a normal IP network, so it is one operation start instruction from the central operation panel. The apparatus is capable of easily operating these complicated operations, and can associate necessary information of measurement data, target waveform data, and image data.

  The vibration control device generates not only the trajectory condition data obtained from the vibration acceleration / displacement data of the actual vehicle but also the numerical estimation of the trajectory condition by a host system (not shown) to generate a target vibration waveform. , It can be received by the test equipment because it is passed through the communication means of the IP network, and the vibration conditions such as the target vibration can be set and the vehicle or carriage can be vibrated by the shaker, and the characteristics change including the specimen (vehicle or carriage) It has become a device having a function to correct.

  According to the above-described embodiment, it is possible to faithfully reproduce and simulate rail running, and to evaluate the dynamic behavior and performance of railway vehicle mounted equipment during actual vehicle running in a short period of time and at low cost under various vibration environments. Can be grasped.

  It is also possible to simulate vibration by processing vibration reproduction of a track abnormal state and a cart abnormality during traveling with a PC or the like.

  In addition, by simulating vibration equivalent to that of a real vehicle while running on the vehicle side with an arbitrary run curve, it is possible to reproduce and simulate the equivalent of a real vehicle faithfully. It is possible to grasp the grasp and the improvement of the performance of the railway vehicle and the safety of the operation in a short time and at a low cost.
