摘　　要：地铁列车救援演练过程中,因司机的不恰当操作导致险情及事故时有发生。针对此问题,文章基于Simulink模块建立地铁列车纵向动力学模型,确定最不利工况,对列车救援工况下车钩力进行仿真分析,通过研究不同阶段紧急制动时全列车的车钩力分布规律,提出救援演练制动操作方式优化建议,为地铁列车司机救援演练制动操作方式的合理性提供依据。In the process of metro train rescue training drill,improper operation of a driver leads to risk situations and accidents frequently.In order to solve these problems,this paper establishes a model of metro train longitudinal dynamics based on Simulink module,determines the most unfavorable working conditions,simulates and analyzes the coupler force under the train rescue working conditions,studies the coupler force distribution pattern of the whole train during emergency braking in different stages,and puts forward the optimization suggestions for the braking operation mode of rescue training,so as to provide reference for metro train drivers in rescue training to improve the braking operation mode with the optimized basis.
