电子万能试验机形变测量标准

Standard for deformation measurement of electronic universal testing machine

通过形变测量装置来测量，它是用来测量试样在试验过程中产生的形变。

It is used to measure the deformation of the specimen during the test.

该装置上有两个夹头，经过一系列传动机构与装在测量装置顶部的光电编码器连在一起，当两夹头间的距离发生变化时，带动光电编码器的轴旋转，光电编码器就会有脉冲信号输出。再由处理器对此信号进行处理，就可以得出试样的变形量。

There are two collets on the device, which are connected with the photoelectric encoder installed on the top of the measuring device through a series of transmission mechanisms. When the distance between the two collets changes, the axis of the photoelectric encoder is driven to rotate, and the photoelectric encoder will have a pulse signal output. Then the processor can process the signal and get the deformation of the sample.
