摘 要：列车纵向动力学性能是影响列车运行质量和运行安全的重要因素。制动工况变换则是导致列车冲动的主要原因。针对列车在制动工况下的纵向动力学分析，详细论述了列车纵向冲动仿真建模的过程。在Matlab/Simulink仿真模块中，可以计算出每节车体的加速度及车钩力大小，为进一步分析并减轻列车纵向冲动提供了理论基础。

Abstract:The performance of train longitudinal dynamics has important effect on quality and safety of train running. Changing to the braking condition is the main cause of the trains longitudinal jerk. On the basis of analysis on longitudinal dynamics of the train which is in braking, it went into detail of the process of the longitudinal jerk simulation modeling. In simulative module of Matlab/Simulink，acceleration and coupler force of each vehicle can be calculated，thus it provides theoretical foundation for further analysis and reduction of longitudinal jerk.
Key words: simulation modeling; longitudinal dynamics; coupler force; Matlab/Simulink
