摘　　要：分析了机车连挂过程的特点和主要影响因素,建立机车在连挂过程中的动力学计算模型;结合多自由度动力学微分方程,根据缓冲器的动力学特征讨论基于NewMark-β法的新解法;应用文章提出的模型和解法进行HXD1型机车的实例计算,并对计算结果进行讨论。This paper analyzes the main features and affect factors of the coupling process between locomotives, builds the dynamics computing model, and considers the muhi-DOF dynamics differential equation and the dynamics feature of buffer, then discusses the new solution method which based on NewMark-β method. Type HXD1 electric locomotives are computed using the dynamics computing model and solution method in this paper, and the computing result is discussed.
