【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、面圧の分布状態を定量的に計測する測定器
に使用する圧力分布測定用ゴム板に関するものである。TECHNICAL FIELD The present invention relates to a rubber plate for pressure distribution measurement used in a measuring instrument for quantitatively measuring the state of distribution of surface pressure.
従来、面圧の分布状態を測定する手段としては、多数の
荷重検出器を計測面に配置する方法や感圧導電ゴム導電

少なくすることができ、測定の再現性が良好且つ直線性
が良好でヒステリシスが少ないことと、低コストである
ことから重視されている。Conventionally, as a means for measuring the distribution state of the surface pressure, there are a method of arranging a large number of load detectors on the measurement surface, a method of measuring the pressure-sensitive conductive rubber conductivity, etc., but it is insufficient in terms of accuracy etc. Yes, as an improved method, the capacitance-based surface pressure distribution measurement system can reduce variations in characteristics due to measurement points, has good measurement reproducibility and good linearity, and has little hysteresis, and low It is emphasized because of its cost.

A sandwich structure sandwiched between two electrode plates is used as a sensor. A high frequency signal is applied to one of the electrode plates, and a high frequency signal is transmitted through the sandwiched spring material to the other electrode plate. Is received by a heterodyne detector.

使用され、いずれも単純な平板形状が採用されていた。
また、感圧紙を使用した圧力分布測定用には、円錐形な
いし山形をした突起を有するゴム板が使用されていたも
のである。The basic structure of this sensor part is as follows:
The spring material (insulator) is sandwiched from both sides by the insulating layer, the electrode layer, and the polyester film, and when the load W is applied in the vertical direction, the thickness t of the spring material is the magnitude of the load. The output of the heterodyne detector is obtained as a function of the load W because it changes with Conventionally, a pressure conductive rubber or a rubber plate having a good impact resilience has been used for this spring material, and a simple flat plate shape has been adopted for each of them.
Further, a rubber plate having a cone-shaped or chevron-shaped protrusion is used for pressure distribution measurement using pressure-sensitive paper.
上記従来使用されているゴム板形状では、いずれも正確
な面圧を測定していないものである。なぜなれば、感圧
部の圧力による変形量は、その部分を形状係数によって
変化するため、加圧面積が広い場合と狭い場合とで、同
じ単位面積当りの力を加えても、ゴムの変形量が異なり
測定値は正確でない値を示すことになる。None of the above-mentioned rubber plate shapes used conventionally measure accurate surface pressure. The reason is that the amount of deformation due to the pressure in the pressure-sensitive part changes depending on the shape factor of that part.Therefore, even if the pressing area is wide and the pressing force per unit area is the same, the rubber deformation The amount will be different and the measured value will be inaccurate.
因って、単位面積当りの圧力とゴムの変形量を常に正し

では、正方形の一辺をａとすると受圧面積はａ２とな

ｂで表示される。従って、 となる。Therefore, it is necessary to solve the problem of the shape of the rubber plate such that the pressure per unit area and the deformation amount of the rubber are always obtained correctly, and to greatly improve the measurement accuracy. The shape factor is a value obtained by dividing the pressure receiving area by the free area, and is one of the indices of the ease of deformation of the rubber plate. For example, in a square prism, if one side of the square is a, the pressure receiving area is a 2 , and if the height of the square prism is b, the free area is 4a.
It is displayed as b. Therefore, Becomes

としては、ヒステリシスロスの小さい、老化性、疲労性
を小さい物性のものを使用しようとするものである。As described above, the shape of the rubber plate of the pressure-sensitive part, that is, the required shape factor formed with a constant pressure receiving area and a constant free area is the primary matter to be solved. For this purpose, it is intended to use a material having a small hysteresis loss, physical properties having a small aging property and fatigue property.

Using natural rubber or silicone rubber that has been peroxide vulcanized with 50 parts or less of rubber relative to 0 parts, the reproducibility of measurement, linearity, and improvement of response speed are aimed at, At least a part of each piece is independently separated by the peripheral groove, and the relationship between the pressure and strain (distortion) in the pressure-sensitive section of each piece is obtained, completely separated from the surrounding pressure distribution state. That is what I was supposed to do. That is, the grooved rubber plate forms the required shape factor in which the pressure-sensitive portion is separated by the peripheral groove. Therefore, the pressure-sensitive portion formed on the inner side of the rubber plate in an independent state by the peripheral groove is used as the pressure measuring portion.

Is a rubber flat plate, FIGS. 7- (a) and (b) are explanatory views of the relationship between pressure and strain of the invention of this application, and W is a load,
GRP is a grooved rubber plate. The conventional example is shown in FIG.
As shown in FIGS. (A) and (B), even if a load of the same pressure per unit area of the pressure receiving surface is applied to the rubber flat plate RSP having a thickness h, the strain amounts d 1 and d 2 are as shown in FIG. In the figure, the changes in the pressurizing conductivity and the capacitance should originally show the same measured values, but the figures A and B show different values. That is, as shown in the relationship curve between strain amount and pressure per unit area in FIG. 8, as shown by both curves A in FIG. 6- (A) and curve B in FIG. 6- (B), The B curve shows a larger amount of strain than the A curve.

The relationship between the pressure and strain of the individual pressure sensitive parts becomes constant,
It was found that an error such as the curve B and the curve A does not occur as shown in the figure. It is Fig. 7-
In (a), if the pressure receiving area and the free area (side area of the pressure sensitive portion in the figure) of each pressure sensitive portion are constant, the relationship between pressure and strain will always be constant, and as shown in FIG. Fig. 7-
The strain amount d 3 in (b) has the same value, and a correct measured value can be obtained.
