    为了对激光驱动飞片的冲击应力进行测试,利用PVDF 压电材料,自制了满足测试需要的应力计,并给出了应力计的动态标定曲线.通过对激光驱动复合飞片和单层飞片的冲击应力进行测试分析,可知对于激光驱动飞片起爆系统,应用较厚复合飞片可获得较大的冲击应力以及较长的持续时间,并指出了 PVDF 应力计测试中的若干注意事项.

    PVDF stress gauge was made for experimental studies on shock pressure of laser-driven flyer. The dynamic calibration curve was given. Measurement for pressure wave profile in the experiment research of single and multiple flyer has been made and analyzed, it showed that using more thicker multiple flyer would obtain higher shock pressure and longer duration. Meanwhile, points for attention in the measurement of PVDF have been put forward.
