“…Several parts consisting of power bogie within rail transit mainly are: wheel-set [32] [33], axle box, frame, primary suspension device, secondary suspension device, traction transmission device and basic braking device. Vehicle system was a complex mechanical system with multiple degrees of freedom, and its dynamic performance [34] [35] [36] was usually studied by the analysis method of multi-body system dynamics. In this work, an electro-mechanical coupling dynamic mathematical vehicle model was established based on vehicle system dynamics to study the influence of electric part of traction transmission system on rail vehicle system.…”

As an important component of train speed regulation, traction transmission system is the power source and the main transmission component of traction force. Its dynamic characteristics can affect the dynamic performance of vehicle system to a certain extent. With the rapid development of rail train transportation in China, the running speed of the train continues to improve, the dynamic characteristics of the vehicle is becoming more complex, and the influence of the electrical part of the traction transmission system gradually appears. The motor and gearbox are crucial components of the train power bogie to complete the conversion and transmission of electric energy to mechanical energy, with their dynamic characteristics are most directly affected by the electrical characteristics of the traction system. In this work, a vehicle electro-mechanical coupling mathematical model based on multi-body dynamics was established by explicitly incorporating the electric-induced traction into the transmission system, to study the influence of traction system vibration on vehicle dynamics. The dynamics responses of the lateral and longitudinal vibration on vehicle motor and gearbox were quantitatively analysed from the traction drive system. Compared with the line test, it was observed that 12-times of the fundamental frequency of the rotor has a great influence on the motor and gearbox.
