摘　　要：根据已有的列车制动力模型,介绍了列车制动力仿真程序实现的技术。利用过渡刚度法处理非线性车钩力模型的拐点问题,并通过四阶龙格-库塔法求解列车制动反应方程组,得到了满足工程应用的列车制动力时程曲线。Be based on the existing model of braking force in China, the technology to implement the simulation program of braking force was presented in this paper. The iteration method changing the stiffness of the model was used to process the first kind of inflexion question of the model and the finite dement method was used to solve the equation of braking reaction. Therefore, the time-history which can be applied in engineering application has been obtained.
