摘要
根据轮轨接触理论,分析了不同轮轨接触几何匹配关系下的轮轨接触应力情况,指出轮轨接触应力、轮轨接触几何关系、轴重是影响重载铁路轮轨磨损的主要因素,从重载运输装备方面提出了减少轮轨磨损的几点建议。
According to the wheel/rail contact theory, the relation of different geometry matching with wheel/rail and wheel/rail contact stress is analyzed. The results show that the main factors of the wheel/rail wear for the heavy haul train is the wheel/rail contact stress, geometry matching and axle load.And some advices for reduction of the wheel/rail wear in heavy transport equipment are indicated.
