Description

本発明は、被測定物の表面に触れた時の摩擦力（摩擦抵抗）や加速度を触覚して評価・測定するための装置に関する。
The present invention relates to a device for evaluating and measuring frictional force (friction resistance) and acceleration when touching the surface of an object to be measured.

従来、金属、合金、合成樹脂などの試料の表面に塗布した塗膜や被膜、コーティング等の摩擦抵抗を測定する装置は多種多様のものがある。しかし、人が物体の表面に触れた時の触感を定量的に解析して評価することは困難で、例えば、人が化粧品を肌に塗布する際の触感や、人がタオルにふれた時の肌触りを解析して評価を行うことは、化粧品やタオルなどの品質を改良する際に極めて有用であるが、その測定装置は極めて少ない。 2. Description of the Related Art Conventionally, there are a wide variety of apparatuses for measuring the friction resistance of a coating film, a coating film, a coating, or the like applied to the surface of a sample such as a metal, alloy, or synthetic resin. However, it is difficult to quantitatively analyze and evaluate the tactile sensation when a person touches the surface of an object.For example, the tactile sensation when a person applies cosmetics to the skin or when a person touches a towel. Analyzing and evaluating the touch is extremely useful in improving the quality of cosmetics and towels, but the number of measuring devices is extremely small.

このような分析や評価を行うために、例えば特開２００５―１２７７１７号公報に開示されているような触感計が知られている。この従来例では、肌や物品に対する荷重と摩擦力とを同時に測定し、これら物理量の大きさや時間的変化を見ることで、物体の表面の面を評価している。 In order to perform such analysis and evaluation, for example, a tactile meter as disclosed in JP-A-2005-127717 is known. In this conventional example, the surface and the surface of the object are evaluated by simultaneously measuring the load and the frictional force on the skin and the article and observing the magnitude and temporal change of these physical quantities.

しかし、例えば、人が物体に触れる際の触感は、人の手や指先を被測定物体の表面に接触しながら摺動させることで得られるが、上記従来例では、この摺動時の手や指の挙動を正確にとらえることが困難であった。また、人が物体の表面に触れる動作には、能動的に触れるアクティブタッチ、受動的に触れるパッシブタッチ、および自分の手や指などで自分の身体に触るセルフタッチなどがある。特に、セルフタッチする場合には、身体の二つの場所に同時に刺激が加わるため、情報量が多く・複雑である。従来技術では、このような場合において物体表面の特性の摩擦力（摩擦抵抗）や加速度を正確に測定することが困難であった。 However, for example, a tactile sensation when a person touches an object can be obtained by sliding the person's hand or fingertip while making contact with the surface of the object to be measured. It was difficult to accurately capture the finger behavior. In addition, there are an active touch in which a person touches the surface of an object, a passive touch in which the person touches passively, and a self-touch in which his / her hand or finger touches his / her body. In particular, when self-touching, a stimulus is applied simultaneously to two places on the body, so the amount of information is large and complicated. In the conventional technique, it is difficult to accurately measure the friction force (friction resistance) and acceleration of the characteristics of the object surface in such a case.

前記押圧機構１０は、基台１０ａに内蔵されたアクチュエータからなる駆動手段１１と、該駆動手段により移動する可動板１１ｂと、該可動板の一側に取付けた支持台１２と、該支持台に内蔵した昇降機構Ｓに設けた連結軸１２５に連結させた可動保持部１２１と、該可動保持部に取付けたバランス調整手段Ｔと、該バランス調整手段Ｔの先端に取付けた能動センサユニットＫとにより構成してある。この実施形態では、前記バランス調整手段Ｔを所定の距離と所定の速度で移動させる駆動手段１１が設けられている。 The pressing mechanism 10 includes a driving means 11 including an actuator built in the base 10a, a movable plate 11b moved by the driving means, a support base 12 attached to one side of the movable plate, and a support base. A movable holding portion 121 connected to a connecting shaft 125 provided in a built-in lifting mechanism S, a balance adjusting means T attached to the movable holding portion, and an active sensor unit K attached to the tip of the balance adjusting means T It is configured. In this embodiment, there is provided driving means 11 for moving the balance adjusting means T at a predetermined distance and a predetermined speed.

前記支持台１２に内蔵した昇降機構Ｓは、図５に示すごとく、垂直方向に軸支したねじ軸１２２と、該ねじ軸に螺合した連結軸１２５と、前記ねじ軸１２２を回動させる調整つまみ１２３とからなり、該ねじ軸１２２に螺合した連結軸１２５の一端は、前記支持台１２の一側に位置した可動保持部１２１の側面に連結させてある。 As shown in FIG. 5, the lifting mechanism S built in the support base 12 includes a screw shaft 122 pivotally supported in the vertical direction, a connecting shaft 125 screwed to the screw shaft, and an adjustment for rotating the screw shaft 122. One end of a connecting shaft 125 comprising a knob 123 and screwed to the screw shaft 122 is connected to a side surface of the movable holding portion 121 located on one side of the support base 12.

前記昇降機構Ｓは、調整つまみ１２３を時計回り、あるいは反時計回りに回転することにより、ねじ軸１２２に螺合した連結軸１２５はねじ軸１２２を昇降動して可動保持部１２１を上下方向に微動させることができるように設けてある。 The lifting mechanism S rotates the adjustment knob 123 clockwise or counterclockwise, so that the connecting shaft 125 screwed to the screw shaft 122 moves up and down the screw shaft 122 to move the movable holding portion 121 in the vertical direction. It is provided so that it can be moved slightly.

したがって、前記可動保持部１２１は、駆動手段１１の可動板１１ｂに取付けた支持台１２とともに長手方向（図２において左右方向）に往復動し、且つ、支持台１２に設けた昇降機構Ｓにより上下方向に微動可能に形成してある。 Therefore, the movable holding portion 121 reciprocates in the longitudinal direction (left and right direction in FIG. 2) together with the support base 12 attached to the movable plate 11b of the driving means 11, and is moved up and down by the lifting mechanism S provided on the support base 12. It is formed so as to be finely movable in the direction.

前記アクチュエータの駆動手段１１の動作は、前記制御装置２００の制御部２１０により速度を秒速約１００μｍから１００ｍｍの範囲で設定可能とし、移動距離は約１ｍｍから３０ｍｍの範囲で移動可能に設定することができる。また、駆動手段１１は、測定中に摩擦抵抗力が押圧機構１０の測定基準を超えた場合、アクチュエータを瞬時に停止させることにより押圧機構１０が破損するのを防止する機能を備えている。 The operation of the actuator driving means 11 can be set such that the speed can be set in the range of about 100 μm to 100 mm per second by the control unit 210 of the control device 200 and the moving distance can be set to be movable in the range of about 1 mm to 30 mm. it can. Further, the driving unit 11 has a function of preventing the pressing mechanism 10 from being damaged by instantaneously stopping the actuator when the frictional resistance exceeds the measurement standard of the pressing mechanism 10 during measurement.

前記可動保持部１２１に取付けたバランス調整手段Ｔは、上方を開口してコ字形に形成した可動保持部１２１に、両側を支持軸１４１で軸支した連結片１３を枢動可能に取付け、該連結片の軸心方向にそれぞれ延伸させた一方のアーム１４ａの先端に、前記被測定物３０と当接する接触子１８を有した能動センサユニットＫを取付け、他方のアーム１４ｂの後端には調整分銅１５を摺動可能に取付けてある。 The balance adjusting means T attached to the movable holding part 121 is attached to the movable holding part 121 which is open at the top and is formed in a U-shape so that the connecting pieces 13 pivotally supported by the support shafts 141 can be pivoted. An active sensor unit K having a contact 18 in contact with the object to be measured 30 is attached to the tip of one arm 14a extended in the axial direction of the connecting piece, and the rear end of the other arm 14b is adjusted. A weight 15 is slidably attached.

前記バランス調整手段Ｔは、図３に示すごとく、アーム１４ａの先端に設けてある能動センサユニットＫの重力により、支持軸１４１を中心とする下方向のモーメントが作用する。この下方向のモーメントを打ち消すため、調整分銅１５によって上方向のモーメントをアーム１４ｂの一端部に発生させてバランスを調整する。さらに、バランス測定手段Ｔの水平性を容易に調整して確認することができる水準器１４２を連結片１３の上面に設けてある。 As shown in FIG. 3, the balance adjusting means T is acted on by a downward moment about the support shaft 141 due to the gravity of the active sensor unit K provided at the tip of the arm 14a. In order to cancel this downward moment, the balance is adjusted by generating an upward moment at one end of the arm 14b by the adjustment weight 15. Furthermore, a level 142 that can easily adjust and confirm the level of the balance measuring means T is provided on the upper surface of the connecting piece 13.

前記バランス調整手段Ｔは、調整分銅１５の重量を一定とし、この調整分銅１５をアーム１４ｂ上でスライドさせることにより位置を変化させ、これによりモーメントの大きさを調整する方法を用いている。この方法の他、例えば、調整分銅１５の位置を一定としその重量を変える（つまり調整分銅１５を異なる重さのものに付け替える）ことでモーメントの大きさを変える方法でも良く、あるいは両方の方法を組み合わせる（調整分銅１５の重さと位置を変える）方法でもよい。また、調整分銅１５の下部に前記アーム１４ｂと並行に取付けたねじ軸１５ａと、該ねじ軸１５ａに微調分銅１５ｂを螺合して取付けてモーメントの大きさを微調整する方法もある。 The balance adjusting means T uses a method in which the weight of the adjustment weight 15 is constant and the position is changed by sliding the adjustment weight 15 on the arm 14b, thereby adjusting the magnitude of the moment. In addition to this method, for example, the position of the adjustment weight 15 may be fixed and the weight thereof may be changed (that is, the adjustment weight 15 may be changed to one having a different weight), or the magnitude of the moment may be changed, or both methods may be used. A method of combining (changing the weight and position of the adjustment weight 15) may be used. There is also a method of finely adjusting the magnitude of the moment by attaching a screw shaft 15a attached to the lower portion of the adjustment weight 15 in parallel with the arm 14b and screwing the fine adjustment weight 15b to the screw shaft 15a.

上記の上方向のモーメントと下方向のモーメントとが同じとなった状態（平衡状態）では、接触子１８の下面における重量は実質的にゼロとなる。この状態で、接触子１８の下面にかける所望の負荷に応じた重さの荷重分銅を摩擦センサ１６の上部に設けた荷重手段１９上に載置させることで、押圧手段１９の重さが接触子１８の下面にかかる重さとなる。 When the upward moment and the downward moment are the same (equilibrium state), the weight on the lower surface of the contact 18 is substantially zero. In this state, by placing a load weight having a weight corresponding to a desired load applied to the lower surface of the contact 18 on the load means 19 provided on the upper part of the friction sensor 16, the weight of the pressing means 19 is brought into contact. The weight is applied to the lower surface of the child 18.

前記能動センサユニットＫは、図３に示すごとく、被測定物３０と当接する接触子１８にＸ、Ｙ、Ｚ方向の加速度を感知して信号Ｓ２を発信する能動センサ１７と、前記被測定物３０に当接する接触子１８の押圧荷重を調節可能に形成した荷重手段１９と、接触子１８の摩擦抵抗を感知して信号Ｓ１を発信するＸ方向ロードセルからなる摩擦センサ１６を垂直方向の同一軸心上に設けてある。 As shown in FIG. 3, the active sensor unit K includes an active sensor 17 that senses acceleration in the X, Y, and Z directions and transmits a signal S2 to a contact 18 that contacts the object to be measured 30, and the object to be measured. The load means 19 formed so that the pressing load of the contact 18 in contact with the contact 30 can be adjusted, and the friction sensor 16 composed of an X-direction load cell that senses the frictional resistance of the contact 18 and transmits a signal S1 are connected to the same axis in the vertical direction. It is provided on the heart.

前記荷重手段１９は、例えば、嵌合（摩擦センサ１６の上面に設けた窪みに荷重分銅を嵌め込む）、螺合（荷重分銅の下面に設けた突起の外周に雄ねじ部を設けこの突起を摩擦センサ１６の上面に形成した穴に設けた雌ねじ部に螺合する）等の適宜な方法が採られてもよい。 The load means 19 includes, for example, fitting (fitting a load weight in a recess provided on the upper surface of the friction sensor 16), screwing (a male screw portion is provided on the outer periphery of the protrusion provided on the lower surface of the load weight, and the protrusion is frictionally applied. An appropriate method such as screwing into a female screw provided in a hole formed on the upper surface of the sensor 16 may be employed.

ここで、接触子１８は、後記するように被測定物３０の所定面３０ａに所定圧力で接触させた状態にした後、駆動手段１１により可動板１１ｂを移動させることにより、支持台１２に取付けられた可動保持部１２１が可動板１１ｂと共に移動することにより接触子１８が所定面３０ａ上を摺動する。 Here, the contact 18 is attached to the support base 12 by moving the movable plate 11b by the driving means 11 after bringing the contact 18 into contact with the predetermined surface 30a of the object 30 to be measured at a predetermined pressure. When the movable holding portion 121 thus moved moves together with the movable plate 11b, the contact 18 slides on the predetermined surface 30a.

この摺動時において、摩擦センサ１６は接触子１８に作用するＸ軸方向の摩擦力を電気信号に変換して信号Ｓ１を出力する。また、能動センサ１７は接触子１８に作用するＸ軸方向、Ｙ軸方向およびＺ軸方向の加速度を検出して電気信号として信号Ｓ２を出力する。これらの信号Ｓ１、Ｓ２（押圧特性）は、計測部２２０の演算部２２１に送出される。 During this sliding, the friction sensor 16 converts the X-axis direction friction force acting on the contact 18 into an electric signal and outputs a signal S1. The active sensor 17 detects acceleration in the X-axis direction, Y-axis direction, and Z-axis direction acting on the contact 18, and outputs a signal S2 as an electrical signal. These signals S <b> 1 and S <b> 2 (pressing characteristics) are sent to the calculation unit 221 of the measurement unit 220.

前記能動センサユニットＫは、能動センサ１７の下面に接触子１８を交換可能に取付けたことにより、指の触感を有する接触子の他、口紅、パフまたはペンシルでアイラインを引く、さらには刷毛の触感を有する接触子などを交換可能に取付けることができる。さらに、接触子として筆記具、被測定部側に紙を取付けることにより、通常の静摩擦や動摩擦を測定することができる。 In the active sensor unit K, the contact 18 is attached to the lower surface of the active sensor 17 in a replaceable manner, so that an eyeline is drawn with a lipstick, a puff or a pencil in addition to a contact having a touch feeling of a finger. A contact having a tactile sensation can be attached in a replaceable manner. Furthermore, normal static friction and dynamic friction can be measured by attaching a writing instrument as a contactor and paper on the part to be measured.

一方、受圧機構２０は、土台となる架台２１と、この架台２１の上部に設けられた２分力ロードセルからなる摩擦センサ２２と、該摩擦センサ２２上に配置された基台部２３を有している。基台部２３の上に位置した被測定物３０には、測定中に移動するのを防止するため公知の固定手段で該基台部に固定してある。また、被測定物３０の所定面３０ａには、３軸方向の加速度を測定する受動センサ２４が取付けられている。 On the other hand, the pressure receiving mechanism 20 includes a base 21 that is a base, a friction sensor 22 that is a two-component load cell provided on the top of the base 21, and a base portion 23 that is disposed on the friction sensor 22. ing. The object to be measured 30 positioned on the base part 23 is fixed to the base part by a known fixing means in order to prevent movement during measurement. A passive sensor 24 that measures acceleration in three axial directions is attached to the predetermined surface 30a of the object to be measured 30.

前記受動センサ２４は、例えば、被測定物３０の所定面３０ａに取付けられ、接触子１８の摺動の際において所定面３０ａに作用するＸ軸方向、Ｙ軸方向およびＺ軸方向の特性である加速度を検出し、これを電気信号に変換して信号Ｓ３を出力する。また、前記接触子１８が所定面３０ａを摺動した際に、摩擦センサ２２は被測定物３０の所定面３０ａに作用するＸ軸方向の摩擦力、およびＺ軸方向の荷重を電気信号に変換して信号Ｓ４を出力する。これらの信号Ｓ３、Ｓ４は、計測部２２０の演算部２２１に送出される。 The passive sensor 24 is, for example, attached to a predetermined surface 30a of the object to be measured 30 and has characteristics in the X-axis direction, the Y-axis direction, and the Z-axis direction that act on the predetermined surface 30a when the contact 18 slides. The acceleration is detected, converted into an electrical signal, and a signal S3 is output. Further, when the contact 18 slides on the predetermined surface 30a, the friction sensor 22 converts the frictional force in the X-axis direction acting on the predetermined surface 30a of the object to be measured 30 and the load in the Z-axis direction into electrical signals. The signal S4 is output. These signals S3 and S4 are sent to the calculation unit 221 of the measurement unit 220.

前記制御装置２００は、測定装置１における動作を制御するための制御部２１０と、データを表やグラフなどに可視化して表示する表示部２３０とで構成されている。 The control device 200 includes a control unit 210 for controlling the operation of the measuring device 1 and a display unit 230 that visualizes and displays data in a table or graph.

図６は、制御装置２００に内蔵された計測部２２０を示したもので、演算部２２１とプロフィール決定部２２２と記録部２２３とから構成されている。この演算部２２１には、測定装置１の摩擦センサ１６から出力された信号Ｓ１、能動センサ１７から出力された信号Ｓ２、摩擦センサ２２および受動センサ２４からそれぞれ出力された信号Ｓ４、Ｓ３がそれぞれ入力される。なお、記録部２２３は、これらの信号Ｓ１からＳ４の値、および演算部２２１において演算された値（摩擦係数など）が記録される。
FIG. 6 shows a measurement unit 220 built in the control device 200, and includes a calculation unit 221, a profile determination unit 222, and a recording unit 223. The arithmetic unit 221 receives a signal S1 output from the friction sensor 16 of the measuring device 1, a signal S2 output from the active sensor 17, and signals S4 and S3 output from the friction sensor 22 and the passive sensor 24, respectively. Is done. The recording unit 223 records the values of these signals S1 to S4 and the values (friction coefficient, etc.) calculated by the calculation unit 221.

また、演算部２２１には、接触子１８から被測定物３０の所定面３０ａに加えられる重さ、具体的には接触子１８に負荷する分銅を荷重手段１９に手動で載置させた重量を演算部２２１に入力する。なお、荷重手段１９の重量を検出するセンサ（図示せず）を設け、このセンサ出力を演算部２２１に入力する構成としても良いものである。 Further, the calculation unit 221 has a weight applied from the contactor 18 to the predetermined surface 30a of the object 30 to be measured, specifically a weight obtained by manually placing a weight loaded on the contactor 18 on the load means 19. Input to the calculation unit 221. A sensor (not shown) for detecting the weight of the load means 19 may be provided, and the sensor output may be input to the calculation unit 221.

演算部２２１は、これらの入力信号から接触子１８と被測定物３０の所定面３０ａとの摩擦係数（動摩擦係数）を算出する。この算出した摩擦係数の値と、能動センサ１７で感知した加速度信号Ｓ２を変換すると共に、プロフィール決定部２２２に送出される。 The calculation unit 221 calculates a friction coefficient (dynamic friction coefficient) between the contact 18 and the predetermined surface 30a of the object to be measured 30 from these input signals. The calculated friction coefficient value and the acceleration signal S 2 sensed by the active sensor 17 are converted and sent to the profile determination unit 222.

プロフィール決定部２２２は、記録部２２３に記憶された基準プロフィールデータを参照して、演算部２２１から入力された摩擦係数の数値と加速度の数値を組み合わせて対応するプロフィールを決定する。 The profile determination unit 222 refers to the reference profile data stored in the recording unit 223, and determines a corresponding profile by combining the numerical value of the friction coefficient and the acceleration value input from the calculation unit 221.

記録部２２３には、少なくとも１つの基準プロフィールデータが記憶されている。基準プロフィールデータは、摩擦係数と加速度と被測定物３０の所定面３０ａの性状との関係を決定するためのデータであり、例えば、図７に示したごとく、横軸（Ｘ軸）を摩擦係数（μ）、縦軸（Ｙ軸）を加速度（Ｇ）としたＸＹ座標の所定の領域を特定の面の性状（例えば柔らかい、固いなど）のサンプルを基にして検知した値をあらかじめ割り当てたものである。 The recording unit 223 stores at least one reference profile data. The reference profile data is data for determining the relationship between the friction coefficient, the acceleration, and the property of the predetermined surface 30a of the object to be measured 30. For example, as shown in FIG. 7, the horizontal axis (X axis) is the friction coefficient. (Μ), a predetermined area of XY coordinates with the vertical axis (Y-axis) being acceleration (G), and pre-assigned values detected based on a specific surface property (for example, soft, hard, etc.) sample It is.

この例では、ＸＹ座標を平面上で縦横それぞれ３つに分け、合計で９つの領域Ａ１からＡ３、Ｂ１からＢ３、Ｃ１からＣ３に分割している。そして、これら９つの領域に、各領域に対応する面の異なる性状を振り分ける。例えば、Ａ１の領域は「つるつる」感、Ａ２の領域は「しっとり」感、Ｃ１は「ザラザラ」感、Ｃ３は「ギシギシ」感などのごとく事前のサンプル実験などにより決定する。 In this example, the XY coordinates are divided into three in the vertical and horizontal directions on the plane, and a total of nine areas A1 to A3, B1 to B3, and C1 to C3 are divided. Then, different properties of the surface corresponding to each region are assigned to these nine regions. For example, the area A1 is determined by a prior sample experiment, such as “feeling smooth”, the area A2 being “moist”, C1 “feeling rough”, and C3 “feeling”.

ここで、被測定物３０の所定面３０ａによっては摩擦係数と加速度とが同じ場合でも、接触子１８に加わる荷重の大きさにより性状が変化する場合があることから（例えば被測定物の面が柔らかい場合）、通常は、基準プロフィールは複数の異なる荷重に対してそれぞれ基準プロフィールが設けられている。 Here, depending on the predetermined surface 30a of the object to be measured 30, even if the friction coefficient and the acceleration are the same, the property may change depending on the magnitude of the load applied to the contact 18 (for example, the surface of the object to be measured is Usually, the reference profile is provided for each of a plurality of different loads.

なお、上記の能動センサ１７および受動センサ２４の少なくとも一方において検知される加速度の大きさ（振幅）や周期は、信号Ｓ３、Ｓ４として記録部２２３に記録される。ここで、上記の加速度の周期は、摩擦中のスティック＆スリップ（摩擦面の付着、滑りの繰り返し）の発生頻度を表し、また加速度の大きさないし測定された値（Ｇ）はその強さを表す。よって、測定された加速度の周期と大きさから摩擦中の状態を把握することができる。即ち、加速度の周期及び大きさ（Ｇ）が小さければ、滑りの滑らかさが実感できる状態（例えば、氷が氷の上を滑る状態）であり、また、これら加速度の周期と大きさが大きい場合には、滑りが滑らかではない状態である。 Note that the magnitude (amplitude) and the period of acceleration detected by at least one of the active sensor 17 and the passive sensor 24 are recorded in the recording unit 223 as signals S3 and S4. Here, the period of acceleration described above represents the frequency of occurrence of stick-and-slip during friction (attachment of friction surface, repetition of sliding), and the acceleration is not increased or the measured value (G) indicates its strength. Represent. Therefore, the state during friction can be grasped from the cycle and magnitude of the measured acceleration. That is, if the period and magnitude (G) of acceleration are small, it is in a state where the smoothness of sliding can be realized (for example, the condition where ice slides on ice), and the period and magnitude of these accelerations are large. In this state, the slip is not smooth.

（動作説明）
次に、以上の構成を有する実施例の測定装置１の動作を説明する。
まず、測定前の準備作業として、押圧機構１０において、バランス調整手段Ｔの調整分銅１５を調整して被測定物３０の所定面３０ａに当接する接触子１８の下方への押圧力をゼロにして平衡状態とする。 (Description of operation)
Next, operation | movement of the measuring apparatus 1 of the Example which has the above structure is demonstrated.
First, as a preparatory work before measurement, in the pressing mechanism 10, the adjustment weight 15 of the balance adjusting means T is adjusted so that the downward pressing force of the contact 18 that contacts the predetermined surface 30a of the object to be measured 30 is made zero. Equilibrate.

一方、受圧機構２０の基板２３の上に測定する被測定物３０の測定対象となる所定面３０ａを上向きとした状態で載置し、所定面の一側に受動センサ２４を取付ける。なお、基台部２３には、測定中に被測定物３０がずれるのを防止するため、適宜な固定方法が採られる。 On the other hand, the pressure sensor 20 is placed on the substrate 23 of the pressure receiving mechanism 20 with the predetermined surface 30a to be measured to be measured facing upward, and the passive sensor 24 is attached to one side of the predetermined surface. In addition, in order to prevent the to-be-measured object 30 from shifting | deviating during a measurement in the base part 23, an appropriate fixing method is taken.

次いで、受圧機構２０の基台部２３に載置した被測定物３０の上面に、押圧機構１０の接触子１８の下面が測定する所定の荷重分量を荷重手段１９に載せる。上記の準備作業が完了した後、被測定物３０の所定面３０ａの測定を行う。即ち、摩擦センサ１６の上部に所定の重量の荷重分銅を荷重手段１９に載置させることで、接触子１８の下面から所定面３０ａの上面に当該重量に対応する荷重をかけることができる。この状態で、駆動手段１１を作動させることにより、接触子１８の下面が所定面３０ａ上を摺動する。 Next, a predetermined load amount measured by the lower surface of the contact 18 of the pressing mechanism 10 is placed on the load means 19 on the upper surface of the measurement object 30 placed on the base portion 23 of the pressure receiving mechanism 20. After the above preparatory work is completed, the predetermined surface 30a of the measurement object 30 is measured. That is, a load corresponding to the weight can be applied from the lower surface of the contactor 18 to the upper surface of the predetermined surface 30a by placing a load weight of a predetermined weight on the load means 19 on the friction sensor 16. In this state, when the driving means 11 is operated, the lower surface of the contact 18 slides on the predetermined surface 30a.

この摺動の際において、次の（１）、（２）の測定を行った。なお、この摺動の速度、つまり駆動手段１１による接触子１８の移動速度は、制御部２１０により速度を秒速約１００μｍから１００ｍｍの範囲で任意に設定し、移動距離は約１ｍｍから３０ｍｍの範囲で左右動可能に設定する。その際、駆動手段１１は、測定中に摩擦力（摩擦抵抗）が押圧機構１０の測定基準を超えた場合には、アクチュエータを瞬時に停止させて押圧機構１０が破損するのを防止することができる。
（１）接触子１８に加わる摩擦力および加速度の経時変化。
（２）被測定物３０の上面に加わる摩擦力および加速度の経時変化。
そして、荷重分銅からなる荷重手段１９の重さを段階的に変化させ、それぞれの場合において上記（１）、（２）の測定を行う。ここで、荷重手段１９を段階的に変化させたり、接触子１８の移動速度を変化させて行う測定は、絶対的なものではない。このような荷重の変動、速度の変動による測定は、測定者の目的に応じて適宜設定される。例えば、乾燥した剛体の測定物同士の場合は、上記（１）及び（２）の測定値（摩擦力、加速度）は同じになる。しかし、触覚評価の測定を行う場合、測定物の片方または両方に弾性（軟らかさ）を有することがある。この弾性によって、上記の（１）と（２）の測定値（摩擦力、加速度）に相違または変化が現れる。即ち、この相違または変化によって触る側の触覚（アクティブタッチ）と、触られる側の触覚（パッシブタッチ）を数字的に把握することができ、触感の定量的な解析ができる。 During the sliding, the following measurements (1) and (2) were performed. The sliding speed, that is, the moving speed of the contact 18 by the driving means 11 is arbitrarily set by the control unit 210 in the range of about 100 μm to 100 mm per second, and the moving distance is in the range of about 1 mm to 30 mm. Set to move left and right. At that time, when the frictional force (friction resistance) exceeds the measurement standard of the pressing mechanism 10 during the measurement, the driving unit 11 can instantaneously stop the actuator to prevent the pressing mechanism 10 from being damaged. it can.
(1) Changes in frictional force and acceleration applied to the contact 18 over time.
(2) Changes in frictional force and acceleration applied to the upper surface of the measurement object 30 over time.
And the weight of the load means 19 which consists of load weight is changed in steps, and the measurement of said (1) and (2) is performed in each case. Here, the measurement performed by changing the load means 19 stepwise or changing the moving speed of the contact 18 is not absolute. Such measurement based on load fluctuations and speed fluctuations is appropriately set according to the purpose of the measurer. For example, in the case of dry, rigid measurement objects, the measurement values (friction force, acceleration) of (1) and (2) are the same. However, when measuring a tactile evaluation, one or both of the objects to be measured may have elasticity (softness). Due to this elasticity, a difference or change appears in the measured values (friction force, acceleration) of the above (1) and (2). That is, by this difference or change, the tactile sensation on the side to be touched (active touch) and the tactile sensation on the side to be touched (passive touch) can be grasped numerically, and the tactile sensation can be quantitatively analyzed.

上記のようにして得られた接触子１８に加わる摩擦力と荷重手段１９で負荷した重量から、演算部２２１において摩擦係数（動摩擦係数）を算出する。この算出した摩擦係数（動摩擦係数）と、能動センサ１７により検知された加速度は、プロフィール決定部２２２に入力される。プロフィール決定部２２２は、記録部２２３に記憶された基準プロフィールデータを参照して、演算部２２１から入力された摩擦係数の数値と加速度の数値の組み合わせに対応するプロフィールを決定する。 From the friction force applied to the contactor 18 obtained as described above and the weight loaded by the load means 19, the calculation unit 221 calculates a friction coefficient (dynamic friction coefficient). The calculated friction coefficient (dynamic friction coefficient) and the acceleration detected by the active sensor 17 are input to the profile determination unit 222. The profile determination unit 222 refers to the reference profile data stored in the recording unit 223 and determines a profile corresponding to the combination of the friction coefficient value and the acceleration value input from the calculation unit 221.

この決定されたプロフィールは、例えば、表示部２３０による表示によってユーザーに伝えられる。表示は、公知の表示手段、例えばＬＣＤ、ＬＥＤ，液晶などによる画面表示、音声出力手段（例えばスピーカ）による音声表示などが使用される。画面表示と音声表示を併用してもよい。この画面表示手段（例えばＬＣＤやＬＥＤなど）および音声出力や画面表示を行うための公知の構成を制御部２１０の内部あるいは外部に設ければ良い。 The determined profile is transmitted to the user by display on the display unit 230, for example. For the display, known display means, for example, screen display by LCD, LED, liquid crystal or the like, sound display by sound output means (for example, speaker), etc. are used. Screen display and audio display may be used in combination. This screen display means (for example, LCD, LED, etc.) and a known configuration for performing sound output and screen display may be provided inside or outside the control unit 210.

（実施例１）
以下に、実施例１を説明する。この実施例１では、接触子１８の底面部分をウレタン樹脂で構成すると共にこの底面に深さ０．１５ｍｍの溝を０．５ｍｍの間隔で多数設けたものを用いた。このような溝を設けることで、接触子１８の底面を人の指紋パターンに類似した状態にすることができ、人が指で物に触れた時の状況を再現できる。 Example 1
Example 1 will be described below. In Example 1, the bottom surface portion of the contactor 18 was made of urethane resin, and a plurality of grooves having a depth of 0.15 mm were provided on the bottom surface at intervals of 0.5 mm. By providing such a groove, the bottom surface of the contact 18 can be in a state similar to a human fingerprint pattern, and the situation when a person touches an object with a finger can be reproduced.

上記の接触子１８を被測定物３０の所定面３０ａの上面に載せると共に、重量５０ｇの荷重分銅からなる荷重手段１９をＸ方向ロードセルからなる摩擦センサ１６の上部に載置させた。この状態で駆動手段１１を作動させ、図２において右方向に１０ｍｍ／秒の速度で３０ｍｍ移動させることにより、接触子１８は被測定物３０の所定面を摺動させた。 The contact 18 was placed on the upper surface of the predetermined surface 30a of the object 30 to be measured, and the load means 19 made of a load weight having a weight of 50 g was placed on the friction sensor 16 made of an X-direction load cell. In this state, the drive unit 11 is operated and moved in the right direction in FIG. 2 by 30 mm at a speed of 10 mm / second, so that the contact 18 slides on a predetermined surface of the object 30 to be measured.

図８に、上記の摺動時において、Ｘ，Ｙ，Ｚの３軸方向の加速度を測定する能動センサ１７から出力された加速度G（Ｘ軸方向の加速度成分）の変化、および摩擦センサ１６により検出された摩擦力から計算された摩擦係数μを示した。これら加速度Ｇと摩擦係数μの大きさ及び変化（周期）から、被測定物３０の所定面３０ａにおける触感を求めることができ、触感の定量的な解析ができる。 FIG. 8 shows a change in acceleration G (acceleration component in the X-axis direction) output from the active sensor 17 that measures acceleration in the three-axis directions of X, Y, and Z, and the friction sensor 16 during the sliding. The friction coefficient μ calculated from the detected friction force is shown. From the magnitude and change (cycle) of the acceleration G and the friction coefficient μ, the tactile sensation on the predetermined surface 30a of the object to be measured 30 can be obtained, and the tactile sensation can be quantitatively analyzed.

例えば、加速度Ｇと摩擦力μが小さいＡ１領域の場合（さらさらした触覚）を測定できる。加速度Ｇを一定にし、摩擦力μを変化させることにより、Ａ２領域（しっとり触感）に変化する状態を検知することができる。また、摩擦力μが小さい状態で加速度を大きくするとＡ１の領域からＣ１領域（ざらざらした触感）を検知することができる。したがって、加速度Ｇと摩擦力μをそれぞれ大きくすると肌触りがＣ３領域（ギシギシした触感）のように、変化の状態を検知することができる。 For example, it is possible to measure the case of the A1 region where the acceleration G and the frictional force μ are small (free touch). By making the acceleration G constant and changing the frictional force μ, it is possible to detect a state changing to the A2 region (moist touch). Further, when the acceleration is increased with the frictional force μ being small, the C1 region (rough tactile sensation) can be detected from the region A1. Therefore, when the acceleration G and the frictional force μ are respectively increased, it is possible to detect the change state of the touch as in the C3 region (scratching feel).
