摘　　要：针对行波超声马达的一种结构,通过等效简化其复合材料定子的模型,推导了定子谐振频率的近似计算方法;还利用有限元法分析计算了定子的振型及其谐振频率;两种方法的结果基本相符,说明基于简化模型的近似计算方法能够反映定子振动的实际情况,这有益于定子结构设计中合理确定相关参数,提高马达的效率和性能。Aimed at the structure of ultrasonic motor with wave traveling, it presented an approximate calculating method of stator resonance frequency by simplifying composite material of stator model.With FEM the stator vibration mode and resonance frequency were given.As the similar results of two methods,it showed that the approximate method on the basis of simplified model could reflect reality of stator vibration.This was useful to define reasonably relevant parameters in construction design, and to raise efficiency and function of motor
