Abstract: A calculating device of the stiffness measurement device pressurizes an object to be measured with a predetermined pressure and the stiffness of the object to be measured in the squeal frequency band is calculated based on an inclination of a stress-displacement performance curve immediately after a start of depressurization after the pressurization. According to this device, there is no need to oscillate the object with a high frequency band and there is no need to enhance the stiffness of the housing of the measurement device, which leads to a downsizing of the device. Further, there is no need for measuring of acceleration speed of the object to be measured and accelerator can be eliminated to reduce the cost of the stiffness measurement device.

Abstract translation: 刚度测量装置的计算装置以预定的压力对被测量物体进行加压，并且基于紧接着开始后的应力位移性能曲线的倾斜度来计算在尖峰频带中的被测量物体的刚度 加压后减压。 根据该装置，不需要以高频带振荡物体，并且不需要增强测量装置的壳体的刚度，这导致装置的小型化。 此外，不需要测量被测量物体的加速度，可以消除加速度，以降低刚度测量装置的成本。
