摘　　要：通过对LMA型踏面磨耗及镟修情况的深入分析,探讨了当前轮对旋修的应用现状,提出了LMA性踏面薄轮缘的优化设计方案,采用细化为以0.1 mm为间隔的旋修模板可以有效减低轮对的旋修量,实现经济性旋修的目的,提高轮对的使用寿命。Through a detailed analysis of the LMA-type tread wear and turning conditions, the current application status of wheel-set lathe maintenance was explored. An optimized design solution for LMA-type tread thin wheel rim was proposed. The use of a refined turning template with a 0.1 mm interval can effectively reduce the amount of wheel-set turning and achieve the goal of cost-effective maintenance, thereby improving the service life of wheel-sets.
