【Abstract】 With respect to 3D visual modelling and simulation of rail vehicles, and based on the Object Oriented technology, mechanics principles concerned and computation architecture for nonlinear dynamics simulation of rail vehicles in the absolute space are described, including especially the complete application of the Hertz elastic theory in wheel rail spatial collision. With the implemented software VSDS, simulation results are reported for the passenger car on the curve track case of Manchester Benchmarks. It is pointed out that nonlinear dynamics simulation of rail vehicles in the absolute space is feasible and convenient.更多还原
