摘要
分析了列车运动的力学模型,并概述了影响牵引计算的各项分力得出方法。在此基础上利用Simulink的资源环境,形成了运行计算、性能计算、线路数据处理、制动力计算、综合控制等多个相对独立、易于参数修改和扩展的模块,以分别完成不同的功能。最后经过功能封装和输入输出连接,构建了一个完整的列车牵引计算和运行仿真模型,该模型可有力地支持列车牵引系统设计和列车线路运行分析。
In this paper, the mechanical modet of train movement was analysed, and numerous factors which influence each component of train traction calculation were summarized. Based on Simulink, many modules which include operating calculation, performance cal- culation, railway line data processing, braking force calculation and comprehensive control are built to perform different functions, and these modules are relatively independent, easily modified and＇extended. A model of traction calculation and operation simulation model is built after the modules are packaged and connected in-out. The results show that the model can effectively be used to design train traction system and analyse train operation in railway line.
