摘要：
The gear transmission system of the railway vehicle is the key part to transmit power for the Electric Multiple Unit(EMU). Its dynamic vibration affect the operation safety and the dynamic characteristics of the vehicle. It is necessary to study the dynamic characteristics of transmission system of the high-speed EMU to obtain the forces and accelerations of the gears. Based on the parameters of a certain type of CRH, a rigid-flexible coupling dynamics model of railway vehicle is established. A flexible transmission system dynamics model is setup and it is included in the vehicle system dynamics model. With numerical method, the dynamics of the transmission system is obtained. The simulation results show that the forces acted on the gears get larger when the operation speed of the vehicle increases. The vibration of the transmission system affect the vibrations of the bogie frame, motor and gearbox, but has hardly effects on the vibration of the carbody because of the secondary suspension system and the huge mass of the carbody. The new railway vehicle-gear transmission coupling dynamics model is useful to investigate the dynamic characteristics of the gear transmission system of the high-speed train. © 2019 Journal of Mechanical Engineering.
