铁路是国民经济大动脉、关键基础设施和重大民生工程，是综合交通运输体系的骨干和主要运输方式之一。钢轨作为轨道交通的重要承载部件， 承受来自车轮周期载荷的作用，其表面会产生滚动接触疲劳层。在随后的过程中，裂纹从滚动接触疲劳层萌生、扩展，从而导致钢轨病害的产 生。同时，多场耦合 ( 强机械力、电场 / 磁场 ) 、广域环境 ( 高寒、湿热、风沙、腐蚀介质等 ) 以及极端工况 ( 高速、高周、强振 ) 的协同作用， 致使钢轨表面产生擦伤、磨耗、波磨、剥落、鱼鳞纹、压溃、锈蚀等诸多损伤。或将破坏钢轨原始设计廓形，恶化轮轨接触状态，增大列车运行 噪声和振动，加速轨道交通系统关键零部件的失效，降低列车运行的舒适性、安全性和稳定性。如果对钢轨进行科学打磨，即可达到延长钢轨使 用寿命的效果，减少大量的经济损失。 钢轨打磨砂轮是损伤钢轨 "刮骨疗伤"的"手术刀"，其性能直接决定钢轨打磨车作业效率和打磨后钢轨表面质量。 01 中国钢轨打磨车砂轮发展现状及未来趋势 钢轨打磨技术可有效去除钢轨病害，延长钢轨的使用寿命，提高列车运行的舒适性、安全性和稳定性。随着经济发展对线路运能提升的迫切需 要，以预防、养护为主的预防性打磨将是未来的主 ...
