Dynamic Analysis of Support System of Permanent Magnet Traction Motors for High- Speed Trains
During the operation,the high speed train will be subject to random vibration load induced by the roughness of the rail and will cause the vibration.Traction motor is critical component of traction system for high-speed train.It is subject to not only static loads,but also random vibration load.This kind of random vibration load may easily lead to fatigue damage of the structure,which will finally cause adversely effect to the motor.Thus,in this paper,a 3-dimension model of the support system of traction motors in high-speed train applications is built,and the static and modal analyses are undertaken using finite element calculation software.The simulation results confirm that the support system is robust enough to meet the design requirements of strength and stiffness.Furthermore,it has a larger margin of safety in a typical case which meets the technical requirements for safe operation of the high-speed train.
