机车车辆在轨道上运行的动力学可视仿真

Dynamical visualized simulation of vehicle running on the track

机车车辆在轨道上运行是一个动力学过程 ,也是一个运动学过程。本文在数值计算的基础上 ,结合 3维建模研究 ,提出了基于线路函数的动画关键帧车辆运动可视再现方法 ,研究了具体的线路插值方法 ,数据标识和关键帧的生成等。最后 ,在开发的仿真平台上运行 ,取得了较好的效果。

It is not only a dynamical, but also a kinematical procedure that vehicle runs on the track. Based on the numerical simulation and 3 D modeling of the coupled dynamics, a new method, animation generation of key frame based on track line function, is presented in this paper. The research emphasis is put on the track line interpolation, data identification, generation of key frame and so on. Finally, the method is implemented on the developed simulation platform, it shows that the result is feasible.
