摘　　要：对行波型超声波电动机采用的柔性转子结构形式进行了研究,利用三维建模软件Solidworks对一种结构形式的柔性转子进行了建模,并利用其自带的有限元分析软件COSMOSWorks对转子做了静态载荷仿真分析,得到了在一定预压力下柔性转子的最小安全系数、静态位移和应力分布图。实验结果表明:仿真结果对转子的设计和生产装配有重要的参考价值。Based on the study of flexible rotor structure applied in ultrasonic motors,this paper built a flexible rotor 3D model using the software Solidworks,and conducted a static analysis on load by the FEM software COMOSWorks within Solidworks.The minimum safety factor,the static movement and the stress distribuction of the flexible rotor on certain load were obtained.Experimental results show that the simulation results serve a valuable reference for the design and productive assembly of USM rotor.
