缓冲器动力学分析

Dynamic Analysis of Vehicle Buffer

本文基于缓冲器工作中的能量变换关系,分析了调车工况及列车工况中两种不同类型的车辆冲动,即速度型冲动与载荷型冲动。文中用动力学的方法,分析了速差、缓冲器特性曲线形状、缓冲器摩擦特性等对缓冲器吸收能量及最大纵向力的影响。为了更好地评价缓冲器的工作能力,引入了能量储备系数。文中还对缓冲器的改进和发展提出了建议。

Two different kinds of vehicle impulse, i. e., velocity impulse in marshalling and load impulse in train running, are analysed with the principle of energy; and by means of dynamics, the influence of velocity difference between vehicles, the shape of the characteristic curve and the friction characteristic of the buffer and its largest longitudinal force are studied. A new factor called the energy spare coefficient is suggested to evaluate the buffer's working capacity. Besides, suggestions for impro- ving and developing the buffer are also given.
