摘　　要：采用有限元法和ANSYS5.7软件设计Cymbal换能器,并分析了前3阶振动模态。该方法解决了该换能器旋转对称面上存在跃变的应力、应变给设计工作带来的困难。结果表明:ANSYS的计算值与换能器的实测值相近。In this paper,the cymbal transducer has heen designed and its preceding three vibration models have been analyzed use the finite element method and ANSYS 5.7 software.The method has solved the difficulty of the saltatory stress and the strain on the rotation symmetry face of cymbal transducer for bringing the design.The result showed that the count value of ANSYS is good agreement with test result of cymbal transducer.
