将行波超声电机的两相振动简化为两自由度系统，建立了基于模态假定的动力学方程．基于机电类比建立定子系统的传递函数及导纳表达式，通过有限元计算及实验测量确定模型参数，在此基础上建立了定子动力学模型的仿真模型．结果表明该模型可用于进行定子的参数化设计及性能的预测．
The twophases vibrations of the stator of travelingwave type ultrasonic motor were simplified into a system of two degrees of freedom,and a dynamic equation was established sequently based on the mode assumption.The expressions for the transfer function and admittance were deduced based on the equivalent circuit, and as a result the parameters were decided through FEM calculation and experimental measurement. Based on this, a simulating model was set up for the dynamic model.The results showed that the method can be used for the parametric design and performance prediction for the stator of ultrasonic motor.
