Compared with conventional rail transit vehicles,suspended monorail trains(sky trains)have great differences in vehicle structure,which contribute to their unique noise characteristics and underscore the value of researching this mode of transportation.In this study,the vibration noise characteristics of sky trains were explored,based on the source-path-receiver mode,and a low-noise scheme was designed to control vehicle noise indexes.Additionally,a simulation and prediction model for vehicle noise was established by utilizing the statistical energy approach(SEA).Furthermore,verification was conducted through noise path experiments,and the re-sults showed a high degree of consistency with the simulations.Sky trains offer significant advantages over conventional rail transit vehi-cles in terms of noise control,highlighting their ability to better meet noise standards and ensure stable operation.
