铁路钢轨波浪形磨损研究进展

Review of Rail Corrugation Progress

铁路钢轨波浪形磨损会导致铁路车辆和轨道强烈的振动、噪声,影响车辆的运行品质和旅客乘坐舒适度,严重的会导致列车脱轨事故的发生.简要介绍了全世界铁路钢轨波磨的分布情况和基本特征,介绍了我国重载铁路、高速铁路、地铁和城市轨道钢轨波磨特征和对应的线路结构特征.回顾了世界钢轨波磨研究的发展历史,重点评述了近40年来钢轨波磨成因理论的研究现状,讨论了已有理论存在的问题和根治钢轨波磨的措施,介绍了我国目前在治理钢轨波磨方面所采取的对策,并对该领域今后的研究方向进行了展望.

Rail corrugation leads to fierce vibration, strong noise and fatigue of vehicle and track, and discomfort for passengers. Severe corrugation may cause derailment accident. This paper briefly introduces the distribution of railway rail corrugation all over the world and its basic characteristics, and presents the rail corrugation characteristics and structure features of heavy haul track, high-speed railway, subway and urban mass rail in China. Then, it reviews the history of rail corrugation study, and focuses on the recent advances in the theoretical models to understand the formation mechanism of rail corrugation for the past 40 years. Finally, the paper discusses the drawbacks of these models, and the current adopted measures for curing rail corrugation in China. The outlook of rail corrugation study is provided.
