本文根据冲击波加载铁电陶瓷的换能原理,建立了斜冲击波加载PZT柱形组件的电响应珲论模型。所考虑的换能装置特点是:(1)柱形组件由n块PZT空心圆盘并联堆叠而成:(2)PZT样品在冲击波压缩区具有恒定电导率r:(3)外电路由串联的电感L和电阻R以及并联电容C_p组成。数值计算结果表明,这种柱形爆电换能器用来提供大电流,大能量(如2000A、100J)是适宜的。
In this paper, based on the shock wave loading ferroelectric ceramic transduction principle, the oblique shock wave loading PZT cylindrical component of the electrical response theory model. The characteristics of the transducers considered are: (1) The cylindrical assembly consists of n PZT hollow disks stacked in parallel: (2) the PZT sample has a constant conductivity in the shock wave compression zone; (3) the external circuit consists of a series inductance L and resistance R and parallel capacitor C_p. The numerical results show that this type of cylindrical explosive transducer is used to provide high current, large energy (such as 2000A, 100J) is appropriate.
