Analysis of Vibration Excitation of Transmission Gear System for Pure Electric Vehicle

Abstract

We use an established transmission gear system to analyze its dynamic response. First, a brief description of the modeling process is given. Then, we listed the dynamic equations of gears, shafts and bearings. New mark- method was used to solve the equations and Fourier transform was used to obtain the frequency domain response. Finally, we analyze the dynamic response and the factors which can influence the dynamic response.
