摘要
以天津地铁9号线为背景,介绍LDP Ⅲ型弹性减磨护轨的设计原理,分析小半径曲线侧面磨耗形成的原因,并对LDP Ⅲ型弹性减磨护轨在城市轨道交通中小半径曲线上减轻轮轨磨耗效果进行分析。
Taking Tianjin metro line 9 as an example,the paper introduces the design principle of LDP HI type elastic less-wear guard rails,makes analysis of the causes of the small radius curve rail side wear development.The reducing wheel-rail wear effect on the small radius curve with the LDP III type elastic less-wear guard rail on urban rail transit are briefly analyzed.
