| 摘 要： | 本文运用弹性力学中的薄壳理论，分析了径向极化压电陶瓷圆管换能器的振动特性，并在此基础上推导出换能器等效电路的特性阻抗，为换能器的设计提供了依据。分析及计算结果表明，本文的理论与以往常用的薄膜理论相比，不仅在物理模型的描述上更为完整准确，在计算精度上也更接近实际。

| Abstract: | The shell theory of elasticity is used to analyze the vibration characteristics of a radial polarized piezoelectric cylindrical transducer. On the basis of analysis, the impedance characteristics of the equivalent circuit of the transducer are derived which can be used for transducer design. The analytic and calculated results show that compared with the membrane theory-which has been used for decades-the present one gives not only more appropriate explanation in physics but also more accurate compute results. |
