摘要(Abstract):

As one of the important noise sources of high-speed railways, the control of wheel-rail noise is of great significance for reducing traffic pollution caused by rail transit. This paper first analyzes the proportion of wheel-rail noise in the exterior noise of high-speed railways. Studies show that wheel-rail noise plays a dominant role in the exterior noise of China's highspeed railways with domestic ballastless tracks and better aerodynamic performance, among which rolling noise is the main component of wheel-rail noise and the core source of exterior noise of high-speed railways. Subsequently, this paper sorts out the commonly used wheel-rail noise control measures and finds that although traditional wheel-rail noise control technologies have formed a complete system of source control and transmission path control, traditional technologies have a poor control effect on low-frequency noise and are difficult to meet the full-band and lightweight noise reduction requirements of high-speed railways. Therefore, the research integrates acoustic metamaterials into traditional noise control technologies. Finally, the research status and application prospects of metamaterials in wheel-rail noise control are summarized. As artificially designed periodic composite materials, acoustic metamaterials have been studied and applied for track vibration reduction and sound barriers, effectively compensating for the shortcomings of traditional control technologies. Relevant research has also begun to move from the laboratory stage to the initial engineering application and industrialization stage, although large-scale practical application still needs to be further promoted.
