摘要：The transmission system of a motor car directly affects the operating reliability and running safety of a high-speed train. This study examines the coupled torsion vibration respons of a transmission system in a vehicle–track vibration environment. It considers the time-varying mesh stiffne
ss, nonlinear damping characteristics, wheel flexible deformation and wheel–rail interactions. The results are compared to tho of previous works as a means of validation. Then, the dynamic characteristics of the transmission system and its coupling effects are investigated along with gear eccentricity, which describes the torsional vibration properties in the vehicle–track coupled system more comprehensively. The results show that the traction torque and gear eccentricity affect the gear meshing, vibration amplitudes redo
