摘　　要：本文以高温超导电机磁体为研究对象,采用电磁场和结构场顺序耦合,重点解决电磁场与结构场之间的数据映射,对磁体低温下受电磁力作用产生的应变进行数值计算和试验验证,从而获得磁体在载流状态下的应变场分布特征,确定磁体结构中较为薄弱的区域,为超导磁体的结构设计和优化提供依据。This paper takes high temperature superconducting(HTS)motor magnet as research object,focuses on data mapping from electromagnetic field to structure field in order to calculate the strain of HTSmagnet in current carrying state with experimental verification,achieves the distribution of strain field,andidentifies weak areas in the magnet structure,which can provide basis for the structure design andoptimization.
