摘要

将整列车看成一个多质点系统，对每节车体进行受力分析，推导出整列车的运动方程，建立多质点动力学模型。基于多质点模型进行牵引、制动、惰行、上坡等多种工况下的列车运行仿真，记录其车钩力分布情况，并对不同编组、不同制动方法下的仿真结果进行了相应的比较，可为列车编组及列车控制提供决策支持。

Abstract

The whole train was regarded as a multi-particle system, the force analysis of each car body was carried out, the motion equation of the whole train was deduced, and a multi-particle dynamic model was established. Based on the multi-particle model, the train operation simulation under various conditions such as traction, braking, coasting, uphill slope and so on was carried out, and the distribution of coupler force was recorded, and the simulation results of different train formation and different braking methods were compared. The results could provide decision support for train formation and train control.
