高速列车运动仿真可视化建模研究

摘要

The three-dimensional dynamic simulation model based on varying parameters is established for the CRH high-speed train, and the real-time transfer and assembly of various train element models during the process of motion are achieved. A high-speed train movement simulation system is developed using Visual C++ 6.0, OpenGL 3D graphics library and the Oracle Database. A comprehensive integrated simulation system between High-speed train movement and three-dimensional line design is established. The experiments show that good simulation results are obtained.%以CRH系列高速列车为研究对象,建立了基于变参数的列车三维动态仿真模型,实现了多种列车单元模型在运动过程中的实时调入和装配,满足了高速列车运动仿真多样性的要求.采用Visual C++ 6.0、OpenGL三维图形库和Oracle数据库开发完成高速列车运动仿真系统,实现高速列车运动仿真可视化建模以及与线路设计之间的有效集成.通过实际应用,取得了较好的仿真效果.
