The lightweight permanent magnet traction system,which can reduce kinetic energy and energy loss during bra-king,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 trac-tion 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.
