摘　　要：为了确切地描述编组场尾部货车溜放的运动规律，科学、合理地制定防溜器的安装方案，提高编组场的自动化水平。采用车辆纵向动力学的方法，分析了编组场尾部车辆溜放过程中存在的各种纵向作用力，重点探讨了缓冲器的特性，导出了缓冲器对的刚度特性，建立了纵向动力学模型，介绍了求解该模型的方法。通过求解该模型可以有效地确定防溜器安装方案，具有重要的实践意义，同时对研究编组场调车作业过程中的车组互撞问题也具有一定的指导作用。For the purpose of illustrating the regularity of running wagons at the rear of marshalling yard, choosing anti running devices reasonably and scientifically, and improving the level of marshalling yard automation, longitudinal forces and the rigidity property of a couple of buffers are analyzed, and then the longitudinal dynamic model of running wagons is established. In addition, the method of resolving the model is introduced. The plan how to set anti running devices, which is of important significance, can be recommended by solving the model. The model can also instruct the research about the impact of different groups of running wagons.
