摘要
从铁道车辆三维可视化建模和仿真要求出发,基于面向对象软件技术,本文叙述了绝对空间中铁道车辆非线性动力学仿真的有关力学原理和计算结构,特别是Hertz理论在空间轮轨弹性碰撞中的完整应用。并用编制的仿真软件VSDS对ManchesterBenchmarks的客车模型进行了曲线通过工况仿真,指出绝对空间中铁道车辆非线性动力学仿真的可行性和实用性。
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.
