摘　　要：为提升浩吉重线路HXD_(1)型机车车轮旋修的经济性,以2024年1~5月期间承修的HXD_(1)型机车C4修旋修车轮数据为样本,开展了系统的数据旋修优化研究。通过对机车车轮直径与轮缘磨耗数据进行分类和数理统计,分析了不同参数之间的磨耗特性及其规律,并提出基于薄轮缘单个车轮与整车轮径差的旋修优化方案,以解决因确保某1个或几个车轮尺寸而导致其他车轮过度旋修的问题。为验证所提优化方案的有效性,对2种不同的车辆旋修策略进行了比较分析。结果表明,基于整车轮径差的旋修优化策略不仅显著减少了机车旋修量,还延长了车辆使用寿命,对于降低机车维护成本和提高整体经济效益具有重要意义。In order to improve the economic efficiency of wheel turning for HXD_(1) locomotives on the Haoji heavy railway line,data on the C4 repaired wheels of HXD_(1) locomotives undertaken from January to May 2024 were collected and optimized for data turning.A statistical analysis was performed to examine the relationship between wheel diameter and rim wear,allowing for an exploration of the characteristics and patterns of wear among various wheel parameters.Subsequently,a grinding optimization strategy was proposed that considers both individual thin-rimmed wheels and overall differences in wheel diameters,addressing the issue of excessive grinding on other wheels when maintaining specific dimensions for one or more wheels.To validate the effectiveness of this proposed optimization strategy,comparative results were analyzed from two distinct wheel grinding approaches.The findings indicated that the total diameter difference-based grinding optimization strategy not only significantly reduced the amount of material removed during locomotive wheel grinding but also extended their service life,thereby playing a crucial role in lowering maintenance costs and enhancing economic viability.
