摘要: 本文根据冲击加载PZT铁电陶瓷材料的电响应理论,讨论了垂直模式的矩形和柱形铁电陶瓷样品含电感负载时的最佳匹配关系、最佳状态的某些特性及最佳装置的设计方法。计算举例表明,理论同已做过的矩形爆电换能实验符合很好。Abstract: In this paper, according to electric response theory of shock loaded PZT ferroelectric ceramic materials, we have discussed the optimal match of rectangular/cylindrical ferroelectric ceramic samples with inductance load in normal mode, some characters of the transducers under the optimal match state and its design method. Examples in the calculation show that theory is in good accordance with the experimental results of the rectangular type.
