在分析列车各向受力和运动状况后建立了列车动力学模型,并编制出计算机仿真程序SCTD。该程序可连续模拟列车从起点站至终点站运行过程中每一时刻所具有的运行条件和受力状况(如机车操作方式、线路平纵断面条件、机车车辆的受力状况等)。因此计算机仿真技术的应用,可为列车动力学的研究提供有效方法。 The train dynamics model was established after analyzing the stress and movement of the train, and a computer simulation program SCTD was developed. The program can continuously simulate the operating conditions and stress conditions (such as locomotive operation mode, line flat longitudinal section conditions, the stress conditions of rolling stock, etc.) that the train has at each moment in its operation from the starting point to the terminal station. Therefore, the application of computer simulation technology can provide an effective method for the study of train dynamics.
