轮轨的相互作用实际上是反复载荷作用下的接触问题。根据Melan定理从理论上对轮轨接触应力问题进行了安定性分析,并得到了轨头内残余应力可能存在的形式。同时,应用三维非赫兹滚动接触应力的计算软件CMEE,从数值上对轮轨接触应力问题进行了安定性分析。
The wheel-rail interaction is actually a contact problem under repeated load. According to Melan theorem, stability analysis of wheel-rail contact stress is carried out theoretically, and the possible form of residual stress in the rail head is obtained. At the same time, the stability analysis of wheel-rail contact stress was carried out numerically using CMEE, a non-Hertz rolling contact stress calculation software.
