时速400km以上高速列车车轮踏面磨耗机理与影响研究
Study on Wear Mechanism and Influence of Wheel Treads for High-Speed Train Exceeding 400 km/h
摘要
Abstract
To improve the operational safety of high-speed trains and optimize the wheel reprofiling strategy,this study constructs an iterative model for wheel tread wear based on Archard's wear theory,analyzes the in-fluence patterns of operating speed,friction coefficient,and operating mileage on wear,and explores the influ-ence mechanism of wheel tread wear on train operational performance.The study finds that the wear depth of the wheel tread presents an M-shaped curve within a reprofiling cycle,with wear concentrated in the area around the rolling circle.Increases in operating speed,operation mileage,and friction coefficient all signifi-cantly enhance the wear rate,and the width of the wear area shows a non-linear expansion trend.While tread wear has little impact on vertical stability and safety,the nominal equivalent conicity,wheel-axle lateral force,derailment coefficient,and lateral Sperling index all increase significantly with the degree of wear.The re-search results provide theoretical support for formulating wheel reprofiling cycles and ensuring the safe opera-tion of high-speed trains.关键词
