Dynamic Analysis of High-Speed Helical Gear Transmission in Pure Electric Vehicle Gearbox
Shock and Vibration
This study is to systematically analyze the influences of time-varying meshing stiffness (TVMS) and meshing impact on the dynamic characteristics of high-speed gear transmission in the two-stage pure electric vehicle (PEV) gearbox, as well as the effect of tooth surface modification on the vibration control. First, the dynamic model was established, and the TVMS and meshing impact were calculated. Then, the vibration characteristics of single-stage and two-stage helical gear transmission weredoi:10.1155/2020/6639372 fatcat:ttvfbrftubaazdq3qn4zsh6laa
