A Review of Recent Research into the Causes and Control of Noise during High-Speed Train Movement

Since the invention of train, problem train noise has been a constraint on development trains. With increases in speed, main from high-speed trains changed rolling to aerodynamic noise, and level frequency range have also significantly. This paper provides comprehensive overview recent advances noise. Firstly, composition is summarized; next, research methods for which include real tests, wind tunnel numerical simulations, are reviewed discussed. We discuss current reduction summarize progress limitations body panels railroad sound barrier technology. Finally, article introduces potential future applications acoustic metamaterials proposes application scenarios specific needs barriers car bodies. synopsis useful platform researchers engineers cope with problems rail future.
