两点应变测量法测试冲击力

Test of Impact force by using two-point strain Measuring Method

运用两点应变测量法的基本原理进行了圆柱杆末端冲击力测试实验，理论值和实测结果取得了一致，验证了其可行性，并进一步发展了两点应变测量法的波形存贮和微机处理技术。

The impact force at the end of a cylindrical rod was tested by measuring strains at two suitable points on it. The theoretical value is in well accordance with the experimental results and the feasibility is verified. The storage and microcomputer processing techniques for the stress wave from two-point strain measurement have been developed.
