摘　　要：文章以350 km/h高速动车组用异步牵引电动机为例,以多物理耦合场基础理论为基础,利用ANSYS软件作为分析计算工具,对异步牵引电动机转子多物理耦合场进行了有限元分析与优化,重点考察了导条长度、护环过盈量等参数变化对异步牵引电动机转子动力学特性的影响,分析了不同的结构参数设置对结构应力分布和变形的影响,并对相关参数进行优化,为转子系统的进一步改进、优化和设计提供了理论依据。Taking asynchronous traction motor for EMU 350 km/h as a example,basing on multi-physical coupling theory,the ANSYS software is adopted to take element analysis on the dynamic property and multi-physical field effect,and the optimization of guide bar and interference fit.In the numerical examples,the effect of parameters of key parts of the rotor,guide bar,end ring,retaining ring,on dynamic property of rotor has been discussed,and the stress distribution and deformation of the structure has been investigated when different structural parameters are set.Some optimizations on guide bar and interference fit value has been carried out,which provide a theoretical basis for the further design and optimization of the rotor.
