Research Status of the Wheel-Suspension System's Vibration Characteristics of Distributed Electric Vehicle

摘要

The industry background of electric vehicle and the advantages of the distributed electric vehicle were presented at first.With that the problems relevant to vibration and noise of this type of vehicle were mentioned as well.According to these phenomena,the research fields to solve the problems were sorted.The overseas and domestic research status of these contents was stated at length.Recent studies didn't meet the requirements of the electric vehicle.It is pressed for the study of the characteristics of the torque pulsation of driving motor and the high-frequency vibration characteristics of electric wheel and suspension system.Some fundamental work of the author's research team towards these problems was introduced as well.
