摘要

Critical speeds are the important indicators when evaluating the dynamic performance of the rail vehicle. In this paper, the whole multi-body dynamic model of the rail vehicle was proposed based on the theory of multi-body dynamics in the software of Simpack. And the linear and nonlinear critical speeds of the whole rail vehicle inspirited by the track spectrum were simulated. This will provide a basis for analyzing on the whole rail vehicle.
