摘　　要：轨道交通的永磁牵引系统轻量化能降低动能和制动时的能量损耗,又可以提高制动性能,是轨道交通行业重点研究领域。本文以北京某地铁线为例,利用ANSYS有限元仿真软件对牵引系统的结构进行了优化设计,永磁牵引系统中VVVF逆变器、SIV逆变器、整流装置分别减重5.84%、4.05%、2.21%,满足相关的标准安全系数要求,同时,优化后的结构目前已经完成了车辆调试、整车牵引系统型式试验以及1000 km空载试运行等,试验结果均为合格。The lightweight permanent magnet traction system,which can reduce kinetic energy and energy loss during braking,and can improve braking performance,has become a key research area in rail transit industry.In this paper,taking a subway line in Beijing as an example,ANSYS finite element simulation software is used to optimize the structure of the traction system,and the weight of the VVVF inverter,the SIV inverter and the rectifier device in the permanent magnet traction system is reduced by 5.84%,4.05%and 2.21%,respectively,which meets the requirements of relevant standards for safety factor.The optimized structure has gone through vehicle debugging,vehicle traction system type test,and 1000 km no-load test,and the test results are all qualified.
