摘要：
Currently, the study on the influence of the suspension parameters of traction motor on the stability of high speed train bogie is mainly focused on the influence on the linear critical velocity of the bogie, rather than the influence on the nonlinear critical velocity.In this paper, according to the type of traction motor suspension on a high speed train, the vehicle bogie dynamic equation was derived.The limit cycle curve of the bogie transverse movement was obtained by continuation algorithm.With the help of the limit cycle, the linear critical velocity and nonlinear critical velocity of the bogie were obtained and the influence of traction motor suspension parameters on linear critical velocity and nonlinear critical velocity was studied.The influence of suspension parameters of traction motor on linear and non-linear critical speed was found to be different.Finally, the relationship between the third resonance coefficient of the system and the linear and nonlinear critical velocity of the bogie was studied by using the Hopf bifurcation paradigm theory.From the results, the larger the real part of the third resonance coefficient, the greater the gap between the linear critical velocity and the nonlinear critical velocity is. © 2019, Department of Journal of the China Railway Society.
