轨面摩擦控制技术防治曲线钢轨侧面磨耗研究

摘要

The rail surface friction control technology can ensure train normal traction and braking performance, and under this premise, the technology reduces the wheel-rail lateral force, and controls the outer rail side wear. The results of the China-made rail surface friction control equipment in field application show that rail surface friction control can be in the premise of not affecting train braking and traction performance, effectively control the friction coefficient of rail surface around 0.35, and the side wear of outer rail can be reduced by 50%.%曲线外轨侧面磨耗是困扰地铁建设和运营部门的难题。轨面摩擦控制技术可以在保证列车正常牵引和制动的前提下，修改轮轨摩擦（粘着）曲线，降低轮轨横向力，抑制外轨侧面磨耗。国产轨面摩擦控制设备的现场应用效果表明，轨面摩擦控制能够在不影响列车制动与牵引的前提下，有效地将轨面摩擦系数控制在0.35左右，外轨侧磨发展速度可降低50%。此创新技术的推广，可保障运营安全，减少运营单位维修养护工作量，提高钢轨服务年限。
