列车运行动态仿真研究

Study on Dynamical Simulation of Running Locomotive

针对列车在轨道线路上运行是一个动力学过程,本文研究了列车动力学的计算机仿真。扩展过去的数值仿真模式,从集成综合仿真的角度,建立了数值、几何简化模型和运动模拟相结合的直观仿真方法,给出了数学、列车几何模型和线路等相关模型的建立方法和相互之间的数据协调方式,并对列车的基于图象帧的动态仿真理论进行了深入的研究,形成了列车动力学综合仿真集成软件,在使用过程中得到了良好的评价。

As to the dynamic process when locomotive running on the track of railway, in this paper, computer simulation of locomotive dynamics is studied. By extending the idea of conventional numerical simulation in the past, and considering system simulation, mathematical model and simplified geometric model and running simulation are integrated, some methods used to construct these models are given, and Image frame based dynamical locomotive simulation are researched deeply. All of these are embodied in the developed locomotive dynamics simulation software named TPLTrain, which has good praise in practice.
