摘要
通过测试东莞轨道交通R2线全线车内噪声,获取了全线的车内噪声水平,由此提出了噪声水平较大区段的治理措施,并基于隧道内铺设有减振轨道、隧道内未铺设减振轨道、高架段铺设有减振轨道三种典型工况下车内噪声数据,对比总结了不同工况下车内噪声频谱特性异同点。
For the purpose of obtaining interior vehicle noise level of Dongguan metro line R2,interior noise test was conducted on the whole metro line,then we can propose control measures on the sections in which interior vehicle noise level is higher. Additionally,based on the interior vehicle noise data of three typical working conditions,tunnel with vibration damping track,tunnel without vibration damping track,viaduct with vibration damping track,the differences and similarities on spectrum characteristics of interior vehicle noise of these three working conditions have been analyzed respectively.
