摘要
通过整体车轮和弹性车轮与轨道垂向耦合动力学仿真和振动模态及声学特性分析 ,对弹性车轮减振降噪机理进行了研究 .对研制的承剪型弹性车轮与整体车轮的声学特性进行了试验比较 。
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.
