摘　　要：为了进一步研究圆柱状水听器的径向振动,运用ANSYS软件建模。通过有限元方法,对同种形状不同尺寸的水听器仿真模型进行径向振动求解,得到了圆柱状水听器的径向共振频率与压电陶瓷和金属负载尺寸之间的关系。通过实验证明仿真计算结果的可靠性,从而为下一步圆柱状水听器的设计和研究提供了坚实的基础。In order to know more radial vibration of a cylindrical hydrophone, modals are built using ANSYS software. Using the finite element method, the radial vibrations of simulating hydrophone modals on different measures and the same shape are calculated. The relationship among the radial resonance frequency, the measure of piezoelectric ceramics and the measure of metallic loads of the cylindrical hydrophone is presented. The tests proved dependability of the calculation results. It is provided the solid basement for the next design and study on the cylindrical hydrophone.
