摘要
随着我国高速铁路的快速发展,轮轨损伤现象变得越来越严重,直接危及高速列车的行车安全。从轮轨材料损伤从发,综述轮轨损伤形式及国内外研究状况;根据轮轨磨损与滚动疲劳损伤之间的耦合作用关系,提出急需进行高速轮轨材料优化匹配的滚滑试验研究,以降低我国高速轮轨损伤。
With the rapid development of high-speed railway, the damage of wheel/rail becomes more and more severe and affects the operation safety of high-speed train. The damage type and the study of wheel/rail were summarized. Based on the coupling relationship between wear and rolling fatiuge damage of wheeL/rail, the experiments on optimization matc- hing of wheel/rail materials should be carried on for alleviating the damage of high-speed wheel/rail material.
