摘要
在爆炸冲击波垂直加载下 ,考虑了介质的松弛现象及其有限电导率 ,建立了PZT95/ 5铁电陶瓷电响应的数学模型。利用这一模型 ,分析了PZT95/ 5在短路、电阻、电容和电感等各种负载下的电响应。理论模型与实验结果较好地符合。
A mathematical model of PZT95/5 ferroelectric ceramics subjected to normal explosive shock loading was suggested.The dielectric relaxation and finite resistive of PZT95/5 were taken into account in this model.Electric equations of PZT95/5 in cases of short circuit,resistive,capacitive and inductive loads were derived.The predictions from this model are in good agreement with previous experimental data.
