摘要

在超声电机定子振动模态有限元分析的基础上，对结构模态截断，仅保留特定的模态，实现了模型降阶。用APDL实现了从有限元分析结果中自动提取特定的模态参数和相应等效电路模型的电学参数。仿真计算了定子的机械和电学响应，与实验数据对比表明，减缩的低阶运动模型保持了原系统的主要特性。

Abstract

Base on the finite element analysis on the vibration mode of the stator of ultrasonic motor

modal truncation method is used to reduce the dimension of finite element model. The modal parameters are automatically obtained from the results by means of APDL (Ansys Parametric Design Language). The dynamic properties of the structure are simulated and tested

and the results are consistent. It is showed that the reduced model can accurately describe the pertinent dynamics of original system.
