摘　　要：为了实现列车运行事故再现系统的要求,采用了Creator环境下铁路线路的建模方法和基于MFC类库的Vega编程方法,给出了建模需要的中心线控制点计算方法以及列车发生事故时脱轨轨迹的计算方法,实现了列车正常运行的视景模拟和列车事故的再现仿真,为今后研究列车脱轨机制提供了较好的可视化参考。Considering the requirements of the train accident reconstruction system,this article discussed the methods of building 3D rail track model based on Creator and computing centerline control points;also utilized the VEGA based on MFC storehouse and simulated the train derailment process.The system successfully modeled the virtual reality simulation of the normal train motion and accident reconstruction;it provided a virtual reference for the research of train derailment process and provided clear understanding of the derailment process in trains.
