| 摘 要： | 对两种厚度的国产PVDF压电薄膜，用轻气炮和激波管进行了冲击加载应力-电荷曲线的标定，并与其它若干种国内外的PVDF标定曲线进行了对比和分析；采用阶梯卸载和同时测量质点速度的方法，研究了PVDF压电薄膜的冲击卸载响应特性，发现有明显的滞后效应存在。

| Abstract: | For two kinds of homemade PVDF piezofilm, the shock loading stress-charge curves were calibrated, using light gas gun and shock tube respectively. Results were compared with some other homemade and overseas' PVDF. By measuring the particle velocity in the step-release experiment, the shock release behavior of PVDF was also studied. The hystersis of PVDF was found obviously. |
