Abstract

Train performance simulation is the foundation of DC analysis and transit line operation. The dynamics of rail trains have been studied for a long time and can be described by established equations. Many simulation programs already exist and are used by the academia and the industry. However, there remain some difficulties in implementing train motion equations to computer simulation so far. The program presented in this paper was developed to solve these difficulties. The authors utilize the modulized feature of MATLAB/SIMLTLINK(R) to construct the train motion block diagram in a straightforward drag-and-drop manner. Train motion equations are then solved using the built-in integration methods equipped with the algebraic loop solver to account for the effects of train speed, position, and line voltage. Also traction characteristics can be described by a small number of data points. Moreover, new blocks can be easily added to their program to include ATC and signaling systems, making it a good building block for DC analysis and other transit line operation assessments.

用于快速交通直流分析的模块化列车性能模拟器

列车性能仿真是直流分析和轨道交通运行的基础。轨道列车的动力学研究已经进行了很长时间，并且可以用建立的方程来描述。许多仿真程序已经存在，并被学术界和工业界使用。然而，目前在列车运动方程的计算机模拟中还存在一些困难。本文提出的程序就是为了解决这些困难而开发的。作者利用MATLAB/SIMLTLINK(R)的模块化特性，以简单的拖放方式构建列车运动方框图。然后使用内置的积分方法求解列车运动方程，并配备代数回路求解器，以考虑列车速度，位置和线路电压的影响。此外，牵引特性可以用少量的数据点来描述。此外，新的模块可以很容易地添加到他们的程序中，包括ATC和信号系统，使其成为DC分析和其他交通线路运营评估的良好构建模块。
