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。
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.
