In the simulation system of Urban railway vehicle traction operation, the running resistance force is simulated usually using constant force or manually alterable force at present. In this paper, the line condition of Shanghai Metro Line 1 is analyzed. The real-time resistance force value at optional position is calculated according to the concrete resistance computational formula and line parameters. The real-time resistance force simulation system of urban railway vehicle is designed and studied in this paper. This system developed by this paper can simulate the traction operation real-time resistance force well.%当前城轨车辆牵引仿真系统的运行阻力仿真方法采用恒负载或手动变负载,不能够完全模拟实际运行线路复杂的负载变化情况.研究并设计了城市轨道车辆实时负载阻力仿真系统,结合对上海轨道交通1号线,介绍了系统的结构框架和设计方法.根据具体的阻力计算公式和线路参数计算列车运行至任意位置时的实时阻力值,并对阻力值进行了分析.结果证明:所开发的系统可以较好地实现车辆牵引的实时阻力模拟.
