摘要
概述了用于铁道车辆的新型液气缓冲器的工作原理,根据列车纵向动力学理论,建立了一对一调车冲击计算模型和仿真计算模型。通过研究4种不同工况下缓冲器动态特性曲线的变化,分析了运行阻力、缓冲介质黏度变化对缓冲器动态特性的影响。
This paper describes the working principles of the hydropneumatic buffer used by railway vehicle.According to the longitudinal dynamics theory of train, the one- to- one impact calculative model and the simulative calculative model are set up.Through the research on the changes of buffer＇ s dynamic characteristic curves under four working conditions, the paper analyzes the influence of nmning resistance and medium viscosity on dynamic characteristic of hydropneumatic buffer.
