摘　　要：以弹性胶泥缓冲器为主要研究对象,分析了弹性胶泥缓冲器的结构特点、工作原理,并建立列车纵向动力学仿真模型,分析缓冲器在不同工况下的动力学特性。通过建立动车组的多体动力学仿真模型,将得出的胶泥缓冲器动态特性用于动车组整车动力学分析模型中,进行紧急制动工况下的仿真计算,并评价其纵向舒适度。结果表明,弹性胶泥缓冲器可以有效降低动车组的纵向冲动,改善乘坐舒适性。Making clastic clay buffer as the main research object,the structure characteristics and working principles of the buffer were analyzed in the paper.On this basis,the train longitudinal dynamics model is created to analyze the buffer's dynamics characteristics in different conditions.By means of establishing the multi-body dynamics simulation model,dynamics characteristics of the buffer can be used in the dynamics analysis model of the EMU to make simulated calculation under emergency braking and evaluate the longitudinal comfort.The result shows that elastic-clay buffer can effectively reduce the longitudinal impulse of EMU,and improve the riding comfort.
