摘　　要：针对重载铁路钢轨波磨检测需求,基于两万吨重载列车运行监控数据与从控机车轴箱垂向振动加速度数据,通过构造“里程-振动”数据,并利用希尔伯特-黄变换算法进行时-频分析,实现对重载铁路钢轨波磨病害的评判与验证,形成融合两万吨重载列车检测监测数据识别钢轨波磨病害的分析方法。Aiming at the requirements of rail corrugation detection in heavy-haul railway,based on the Leak Jet Guardian data of 20,000 t of heavy-haul train and the vertical vibration acceleration data of the axle box of the controlled locomotive,the"kilometrage-vibration"data was constructed and time-frequency analysis was carried out using the Hilbert-Huang Transform algorithm to evaluate and verify the rail corrugation.The analysis method of rail corrugation identification by combining the detection and monitoring data of 20,000 t heavy train is developed.
