本文首先讨论如何严格定义铁道机车车辆上常用的“相对摩擦系数”这一名词术语,接着列举了国内外若干种常见的摩擦减振器的结构型式及其相对摩擦系数的计算公式,并初步讨论了减振器的摩擦力在我国货物列车运行速度范围内所起的作用从而确立选择它的原则。 This article first discusses how to strictly define the term “relative friction coefficient” commonly used on railway rolling stock, and then lists some common friction damper structure types and their relative friction coefficients at home and abroad, and initially discusses The friction of the shock absorber in the operation of China’s cargo train speed range to establish the role of the choice of its principles.
