Abstract

Abstract: In order to truly simulate the moving postures of the high-speed train at run time, based on six degrees of freedom Stewart motion platform, dynamics simulation system and simulation operation interface are developed by VC++ programming language. The dynamics model of high-speed train system is presented in this paper, whose first vehicle is a detailed coupled model including longitudinal, lateral and vertical DOF (Degree of Freedom), and other vehicles are the mass models only with the longitudinal DOF. In the process of the simulation, the dynamics model is updated in real time according to line data and driver's operation, and then dynamics model is solved by a new display integral method (zhai method). The responses of all DOF of high-speed train head car body in different working conditions and control conditions are calculated. The body acceleration is applied to drive the six DOF motion platform forming a simulated driving dynamics platform, which is both physical and virtual. The availability is carried out based on the dynamic simulations and field test results. The simulated driving dynamics system is successfully applied to drivers training.
