电动汽车变速器的振动分析

he electric vehicle is becoming more and more common, due to advantages of convenience, environmental protection and energy conservation,favored by people, but the electric vehicle comfort is also put forward higher requirements, so the article studied the vibration problem of electric vehicle.In this paper, through mathematical method--the transfer matrix method for modeling the electric automobile transmission，then by using three-dimensional modeling software, the motor and transmission are modeled, then did some simulation analysis by using ANSYS software. so the natural frequency of system by two square method , is closer to the actual value. The related basis for the study of the vibration of electric vehicle is provided.
