【Abstract】 Through vertical wheel rail coupled dynamics simulation analysis of the modal and acoustical property for both solid wheel and resilient wheel,the mechanisms on decreasing wheel rail noise and vibration of resilient wheels were investigated.Then,the experimental comparison was performed between a rubber-cushion resilient wheel and a solid wheel.The results yielded manifested that resilient wheels play an active role on decreasing wheel/rail vibration and noise for urban rail vehicles.更多还原
