| 摘 要： | 针对目前轨道交通车站的实际情况,设计并研制可以有效降低列车进出站时产生的轮轨噪声的轨道交通嵌入式声屏障.该声屏障充分利用了轨道床两侧架设通讯电缆的凹型空腔,并依据列车噪声分布进行了针对性设计.同时根据声波的传输规律,利用有限元分析软件ANSYS和边界元分析软件SYSNOISE对嵌入式声屏障的现场声学性能进行仿真研究,得到列车进出站时的现场噪声分布及该嵌入式声屏障的现场声学性能.

| Abstract: | This study based on current situation of urban rail transit,designs and develops an embedded sound-barrier of urban rail transit which can effectively reduce the noise of vehicle passing in and out the station.The sound-barrier sufficiently uses the concave space of both sides of the railway which is used for communication cable,and designs based on distributed noise result of urban rail transit.Based on radiation rules of sound wave,ANSYS and SYSNOISE are used to simulate embedded Sound-Barrier's acoustic performance.The distributed noise result of urban rail transit and the embedded sound-barrier's acoustic performance is obtained. |
