本文介绍B.Paul等人提出的具有任意空间曲面轮廓的弹性物体共曲接触问题的数值计算方法,并将其应用于机车轮轨的非赫兹接触分析。通过对机车凹形踏面车轮在钢轨上的不同接触点求解,首次给出了机车轮轨非椭圆接触情形的数值计算结果,这些结果与实测结果相近。 In this paper, we introduce the numerical calculation method of the common-curve contact problem of elastic objects with arbitrary spatial surface profile proposed by B. Paul et al. And apply it to the non-Hertzian contact analysis of locomotive wheel and rail. By solving the contact points on the rail of locomotive concave tread wheel, the numerical calculation results of non-elliptical contact of locomotive wheel and rail are given for the first time. These results are similar to the measured ones.
