摘要
对夹心式压电超声扭转振动换能器进行了研究,得出了其共振频率方程,给出了切向极化压电陶瓷剪切波的等效声速。对于扭转振动换能器系统设计理论的建立提供了一定的理论基础。
The piezoelectric ceramic ultrasonic torsional sandwich transducers were studied,and the res-onance frequency equation was derived. The speed of effective torsional wave in piezoelectric ceramic slender rods was given. The analysis will provide theoretical base for design and calculation of torsional sandwich ul-trasonic transducers.
