【摘要】 随着铁路的进一步提速以及列车总重的不断增加,对列车的纵向冲动提出了更高的要求,开发新型缓冲器有着十分重要的意义。现介绍铁道机车车辆液气缓冲器的基本结构及其工作原理,并对其动力学特性进行了分析研究。通过与传统的弹簧和橡胶缓冲器的比较,对液气缓冲器的性能进行了分析评价,为液气缓冲器在我国铁道机车车辆上的应用提供了理论依据。更多还原

【Abstract】 With the further speed raising and train′s gross weight increasing,severe request is put forward to train longitudinal impulse.So,it is very important to develop new type buffers.The basic structure and principle of the hydro-pneumatic buffer for railway locomotives and vehicles are summarized.And the static and dynamic characteristics of buffers are analyzed by numerical simulation.Compared with the traditional spring and rubber buffers,characteristics of the hydro-pneumatic buffer are analyzed and appraised,which provide theory basis for the hydro-pneumatic buffer applied on railway locomotives and vehicles.更多还原
