High-speed railway track surface collapse,corrugation,and various wheel-rail surface matching problems will affect the comfort of passengers and even threaten the safety of EMUs.The above-mentioned track defects are not easy to find in practice and will cause extreme deterioration of the wheel-rail contact relationship for a long time,which will seriously affect the service life of the vehicle and the track structure.Based on the high-speed railway comprehensive inspection trains equipped with continuous force measuring wheelsets,the actual wheel-rail force measurement data covering the national high-speed lines obtained in daily inspections are carried out in-depth statistical analysis and on-site comparison,and a brand-new track defect evaluation program can accurately give information such as track defect type,defect severity,specific mileage,etc.,which provides an important basis for the daily inspection and maintenance of the public works department,and has good results in practice.
