摘要

摘要:
为研究60N钢轨350 km/h 18号高速道岔合理的轨距和轨底坡，利用60N钢轨高速道岔关键断面和实测LMA磨耗车轮，基于迹线法原理和Kalker三维非赫兹滚动接触理论，分析不同轨距和轨底坡参数下的轮轨接触几何和力学特性，并与CHN60钢轨高速道岔计算结果进行对比. 结果表明：在保证安全的前提下适当将轨距加宽可改善轮轨匹配关系，提升列车过岔平稳性，减小轮对横移量大于8 mm时的轮轨接触应力和表面滚动接触疲劳因子，延长尖轨使用寿命；轨底坡为1/30、1/40和1/50时，轮轨接触参数相差较小，匹配性能较优；轨底坡为1/10和1/20时，横向不平顺和轮轨滚动接触疲劳因子普遍较大，且1/10轨底坡对车轮磨耗的适应性较差；与CHN60钢轨高速道岔相比，60N钢轨高速道岔的等效锥度普遍更小，列车过岔平稳性更优；车轮磨耗易导致车轮在轮轨过渡区段空转，引起尖轨伤损.

Abstract:
In order to investigate reasonable rail gauge and rail cant of No.18 turnout with 60N rail under the straight passing speed 350 km/h, based on the track line method and Kalker’s 3D non-Herz rolling contact theory, key sections of 60N rail turnout and measured LMA worn wheels were used to analyzed the wheel-rail contact geometric and mechanical characteristics under different rail gauges and different rail cant parameters. The calculation results were compared with those of CHN60 rail turnout. The results show that under the premise of ensuring safety, properly widening the rail gauge can improve the wheel-rail matching relationship, improve the stability of the train went through the turnout, reduce the wheel-rail contact stress and surface rolling contact fatigue factor when the wheelset-lateral displacement is greater than 8 mm, and extend the service life of the rail. When the rail cant is 1/30, 1/40 and 1/50, the wheel-rail contact parameters have little difference and the matching performance is better. When the rail cant is 1/10 and 1/20, the lateral irregularity and wheel-rail rolling contact fatigue factors are generally large, and the adaptability of 1/10 rail cant to wheel wear is poor. Compared with CHN60 rail turnout, the equivalent conicity of 60N rail turnout is generally smaller, and the stability of the train went through the turnout is better. Wheel wear is easy to lead to wheelspin in the wheel-rail transition section, resulting in switch rail damage.
