Random Vibration Analysis on the Vehicle Drive Motor System
As one of the core components of new ener-gy vehicles,the vibration characteristics of the motor sys-tem directly affect the stability of vehicle operation,there-fore,it is necessary to analyze the random vibration intensi-ty in the development stage.In this paper,a motor system is taken as the research object,the modal characteristics of the motor subsystem are analyzed through simulation analysis and experimental test.The dynamic analysis model on the motor system including the tooling is established while ac-curacy of the analysis model is verified by random vibration test,providing support for the analysis of the random vibra-tion strength of the motor.
