摘　　要：为评估动车组车轮在高级修到限条件下的经济效益,以提升维护管理的效率和成本效益,基于实际运用数据优化镟修策略。文章通过对经济数据的深入分析,探讨了高级修条件下镟修车轮的经济优势,并利用车轮检修数据建立了磨耗与镟修的数学模型。最后,文章提出了一种基于高级修到限的镟修策略,指导现场实时镟修作业。研究结果显示,相较于传统的运用修到限策略,采用高级修到限策略可明显降低维修频率,并通过动态调整镟修量决策,实现了对镟修量的合理控制,显著提升了车轮的经济效益与动车组的运行可靠性。This paper evaluates the economic benefits of EMU wheels upon the completion of their advanced repair periods and op-timizes the re-profiling strategy based on actual application data to enhance the efficiency and cost-effectiveness of maintenance manage-ment.Through in-depth data analysis of economic effectiveness,this paper discussed the economic advantages of wheel re-profiling as a complement to advanced repairs,and established a mathematical model of wear and re-profiling based on wheel maintenance data.Ulti-mately,a re-profiling strategy for retirement upon the completion of advanced repair periods was proposed,aimed at guiding on-site re-profiling operations.The research results show that,compared with the traditional strategy of retiring wheels at the end of service repair periods,the strategy of retirement at the end of advanced repair periods can significantly reduce maintenance frequencies.Dynamic ad-justments to re-profiling decision-making allow for the rational control of re-profiling amounts.The proposed strategy can significantly improve the economic benefits of wheels and the operational reliability of EMUs.
