基于库仑定律的滚动轮表面接触应力分析

Contact stress analysis of rolling wheel surface based on Coulomb theory

针对滚动轮表面接触应力的分析误区,基于库仑定律对路面(材料)与滚动轮接触表面的应力进行分析,得出在滚动轮接触表面不仅有接触正应力,而且还有接触剪应力(或摩擦应力)的结论。并根据结论进一步分析,阐明了原分析误区不能解释的问题。

To solve the problem of surface contact stress of a rolling wheel, the Coulomb theory is adopted to analyze the surface stress between the rolling wheel and road material. It is the conclusion that there are contact stress and contact shearing stress on the rolling wheel, the conclusion can explain the contact stress problem.
