摘要：
To address the ubiquitous wheel-rail excitation problem encountered during the operation of high-speed trains, common research methods of wheel-rail excitation were systematically generalized. The factors and action mechanisms of wheel-rail excitations, such as track irregularity and non-circular wheel, were researched, and the formation mechanisms of medium- and high-frequency wheel-rail excitations, such as the polygonal wear of wheels and rail corrugation, were emphatically analyzed. The influence of wheel-rail excitation on the riding quality of high-speed train was discussed in terms of dynamics performance and noise, and that on the service performance of vehicle-rail parts was analyzed in terms of fatigue damage. Considering the existing monitoring technologies and research methods of wheel-rail excitation, the research prospect of wheel-rail excitation of high-speed trains was proposed. Analysis result demonstrates that the field observation, numerical simulation, and experimental simulation are commonly employed to study the wheel-rail excitation. The frictional self-excited vibration of the wheel-rail system, the structural resonance of vehicle-rail components, material characteristics, and process quality are the fundamental causes of wheel-rail excitation. A few indicators, including system structure parameters, operating speed, mileage, load, and line conditions, have impacts on the formation and development of wheel-rail excitation. Although the low-frequency excitation decreases the operation speed in curve segments, it has little influence on the service life of vehicle-rail components. The medium- and high-frequency excitation substantially affect the running quality of the train and maintain the system in the state of medium- and high-frequency vibration for a long time, leading to a structural resonance and exacerbating the fatigue damage of components. Real-time monitoring technology and accurate detection methods can be combined to conduct in-depth researches on the formation and development of wheel-rail excitation. The formation and development of wheel-rail excitation can be restrained or decreased by measures such as optimizing the wheel-rail matching profile, developing the process equipment and intelligent vibration noise reduction devices, and optimizing vehicle-rail the structure and maintenance. © 2021, Editorial Department of Journal of Traffic and Transportation Engineering.
