阐述在考虑了轮轨非绝对刚体的情况下的轮轨接触问题,介绍了轮轨相互作用的内在机理。在弹塑性变形的基础上,研究了轮轨系统中载重对滚动阻力影响问题,即载重与阻力系数的关系。
The wheel-rail contact problem under the condition of non-absolute rigid wheel and rail is considered. The internal mechanism of wheel-rail interaction is introduced. Based on the elastic-plastic deformation, the influence of load on rolling resistance in wheel-rail system is studied, that is, the relationship between load and resistance coefficient.
