矩形扭转压电换能器的研制

Study and manufacture of torsional piezoelectric ultrasonic transducer

本文从压电和机械振动等基本理论出发，首次较系统地建立了短形扭转压电换能器的理论，推导出了频率方程，并通过实验进行了验证。

Based on the piezoelectric and wave equations, the theory of rectangular piezoelectric torsional transducers is established, with the electro-mechanical equivalent circuit and the frequency equation being derived. A satisfactory agreement is obtained between the computed results and experimental.
