摘要

综述了钢轨打磨技术国内外起源以及发展现状，对现阶段钢轨打磨技术的分类进行了介绍，重点介绍了曲线和直线钢轨的打磨策略制定原则；对钢轨廓形设计的主要原则进行了归纳总结；分析研究了打磨作业中打磨量的主要影响因素；提出了钢轨打磨应根据打磨前实际钢轨使用状态，在满足目标廓形、保证打磨深度和消除病害的前提下，使打磨切削量最小；最后对今后钢轨打磨技术研究重点进行了展望。

Abstract

The origin and development status of rail grinding technology at home and abroad was summarized, and the classification of rail grinding technology at current stage was introduced, focusing on the principles of making grinding strategy for curve and straight rail. The main principles of rail profile design were summarized. The main influencing factors of grinding amount in grinding operation were analyzed and studied. It was put forward that rail grinding should be based on rail actual use state, and minimize the grinding cutting amount under the premise of meeting the target profile, ensuring the grinding depth and eliminating the defects. Finally, the research focus of rail grinding technology in the future was prospected.
