摘要
通过刚性车轮和弹性车轮振动模态及频响函数分析 ,对弹性车轮减噪机理进行了研究 ,同时对研制的承剪型弹性车轮与刚性车轮进行了噪声对比试验 ,验证了弹性车轮在缩短噪声衰减时间、改善频谱特性方面显示的减噪优良性能。
Through theoretical analysis of the model and acoustical property for both rigid wheel and resilient wheel, the mechanisms on decreasing wheel/rail noise of resilient wheels were investigated. Then, the experimental comparison was performed between a rubber-cushion resilient wheel and a rigid wheel. The results yielded were inspiring, and they manifested that the resilient wheel plays an active role on decreasing wheel/rail noise for urban rail vehicles.
