| 摘 要： | 等效斜率的概念来自轮对的蛇形运动,它反映了轮对几何蛇形运动的波长.等效斜率通常根据左、右车轮滚动半径差随轮对横移量变化的函数(RRD函数)计算得到.介绍了几种根据RRD函数计算踏面等效斜率的原理和公式,包括UIC 519积分法、简谐线性法、以及概率法等.通过算例比较了等效斜率各种算法之间的差异,并与时域仿真的结果进行了...

| Abstract: | The concept of equivalent conicity of tread comes of the wheelset hunting,which decides the wave length of wheelset hunting.An equivalent conicity is usually calculated by the rolling radius difference and the function of tread.Several algorithms for equivalent conicity including UIC-915 integration method,Harmonic method and UK probability method are introduced,examples are taken to compare the difference of equivalent conicity among these algorithms,and a wave length of wheelset hunting is given through a... |
