【摘要】 对一种多元石英计的冲击动态响应进行了实验研究,实验结果表明,冲击压力低于2 GPa的条件下,多元石英计测量单元压电电流动态响应的基本特征,以及在边缘效应影响下,测量单元压电电流起跳值的降低、斜升幅度的增加,都类似于短路型单元石英计,因而可应用于冲击作用,特别是空间非均匀冲击作用分布等的研究。更多还原

【Abstract】 In this paper,one kind of multi-element quartz shock gauge(MEQSG) has been investigated up to 2 GPa shock pressure.The results show that the piezoelectric currents of active sensing elements are very similar and almost have the same character with the signal of single-element quartz under the same conditions.Signal probing confirms that the initial current jump and current ramping of MEQSG under field fringing’ effect are also very similar with single-element quartz.更多还原
