“…A spring-damping element is used to simulate the fastener to realize the connection between the rail and the slab. Wang and Lei [22] also studied the stick-slip characteristics of wheel-rail contact under different super, standard, and high conditions and found that both the inner and outer wheel-rail systems had the possibility of a stick-slip movement on the small-radius curve of the subway, and the inner wheel-rail system was more likely to cause the formation of rail corrugation. In terms of other research methods, Wang and Lei [21] used the three-dimensional finite-element model of a wheel-rail system to carry out the complex eigenvalue analysis of influence factors for corrugation.…”

Rail corrugation is a serious problem in a railway transportation system, aggravating the operational risk and shortening the lifetime of train–track system. In order to ensure the safety and reliability of the railway system, the detection of rail corrugation is very important. Thus, this study systematically summarizes the recent research progress of rail corrugation. First, this study introduces the definition of rail corrugation and the classification criteria. Then, the formation mechanism of rail corrugation is analyzed in detail, and its adverse consequences are investigated. Further, this study summarizes several main detection methods, which are corrugation-detection methods based on acceleration measurements, wavelet transform methods for corrugation evaluation, computer-vision-based methods for corrugation automatic detection, digital filtering algorithms for rail corrugation detection, and others. In this study, the formation mechanism and detection methods of rail corrugation are systematically described, and various corrugation-detection methods are also introduced in detail. This study not only provides a scientific basis for railway maintenance, but also lays a solid foundation for future experimental design and data analysis. This study can also guide engineering practice to improve the reliability and safety of railway systems. It also provides useful experience for future railway-engineering design and planning, as well as safer and more reliable operation. In general, this study can provide technical support for the detection of rail corrugation to ensure the safety of the rail–track system.
