摘要
随着高速铁路的不断发展,轮轨滚动接触问题愈加突出,因此,倍受国内外学者的关注。轮轨滚动接触问题涉及的范围较广且较为复杂,并在一定程度上引发轮轨的疲劳损伤和波浪形磨损等破坏形式。基于理论分析和试验研究两个方面,着重对轮轨滚动接触的发展历史和研究现状进行了总结和分析,并综述了轮轨滚动接触疲劳和钢轨波浪形磨损的研究现状。从现有的研究成果来看,轮轨滚动接触理论已相对较为完善,而对于高速铁路轮轨滚动接触疲劳损伤的形成机理研究仍未形成系统的理论体系。
With the continuous development of high-speed rail,the problem of wheel/rail rolling contact is increasingly prominent,therefore,attracted the attention of scholars both at home and abroad.Wheel/rail rolling contact problem involved in a wide scope and complex,and to a certain extent,caused fatigue damage and corrugation of wheel/rail,and other forms of destruction. Based on the theoretical analysis and experimental research,the studies focused on the development of wheel/rail rolling contact history and research status at present.From the point of the existing research results,the wheel/rail rolling contact theory is a relatively perfect,whilst the systematic theory of the formation mechanism of high speed railway wheel/rail rolling contact fatigue damage has not established well yet.
