摘要：面对城轨的快速发展，列车的安全与稳定是我们最关注的问题。因此，我们需要对列车的运行状态有精确地判断。牵引计算仿真是一种既实用又可靠的方法，开发设计牵引计算仿真系统对我们研究列车行驶的情况有很大的价值。这不仅会减少列车的安全隐患，还能为我们节省能源。首先，本文先研究城轨车辆牵引计算的基本理论。然后进行MATLAB编程，通过建立人机对话界面，设计出一个能够判断出列车运行状态的仿真系统。在此系统中，通过已知的参数，可以绘制出不同车型的单位合力曲线、速度距离曲线以及时间距离曲线，同时还能计算出能耗值。最后，在本文中，我们会通过比较不同的算例来测试所设计的系统是不是可靠。设计出的仿真系统会大大方便我们对城轨车辆运行情况的判断。43134

Research of Urban Rail Vehicle Traction Calculation Simulation System

Abstract：In the face of the rapid development of urban rail, the security and stability of the train is our most concern. Therefore, we need to have a precise judgment on the running state of the train. The traction calculation simulation is a practical and reliable method, development and design of train traction calculation simulation system for our research has a great value. This will not only reduce the security hidden danger of the train, can also save energy for us. First，In this paper, the basic theory of traction calculation for urban rail vehicles is studied in this paper. And then MATLAB programming, through the establishment of man-machine dialogue interface, designed to determine the status of a train running simulation system. In this system, through the known parameters, we can map the unit force curve, speed, distance and time distance curve, but also can calculate the value of energy consumption. Finally, in this article, we will through comparing the different numerical example to test the designed system is reliable. The simulation system designed will facilitate us to judge the urban rail vehicle running status.
