【摘要】 通过实验介绍了车轮滚动时的轴向滑动系数的测定方法，得出车轮滚动前进时，如果同时存在着轴向滑动（即不同时滚动）时滑动摩擦系数的0．85倍（对接触表面粗糙度），与滚子速度无关。更多还原

【Abstract】 An experiment is given to introduce a way of measuring a wheel’s axial sliding friction coefficient while the wheel is rolling. And we get the result that if the wheel is rolling forward while it is axially sliding, its axial sliding friction coefficient is 0. 85 time as much as its simple axial sliding friction coefficient ("simple" here means that wheel is sliding but not rolling) and that the friction coefficient has nothing to do with the rolling speed.更多还原
