The invention discloses an urban rail transit contact rail system with a noise reduction function. The urban rail transit contact rail system comprises noise reduction devices, and the noise reductiondevices are suitable for C-shaped contact rails and are distributed on noise generation zones of the C-shaped contact rails; the noise reduction devices comprise damping layers and first fixing supports; and the damping layers are fixed into rail cavities of the C-shaped contact rails and are the same as the rail cavities in shape, and the damping layers are fixed into the rail cavities through the one or more first fixing supports, so that the damping layers are tightly attached to the inner walls of the rail cavities. The contact rail system with the noise reduction function is particularlysuitable for a novel rail transit mode adopting an elevated mode, and noise generated by the contact rails during traveling can be effectively reduced.
本发明公开了一种具有降噪功能的城市轨道交通接触轨系统,包括降噪装置,所述降噪装置适用于C型接触轨,且分布在所述C型接触轨产生噪音的区段;所述降噪装置包括阻尼层和第一固定支撑;所述阻尼层固定在C型接触轨的轨腔内并与所述轨腔的形状相同,且通过一个或若干个所述第一固定支撑将所述阻尼层固定在所述轨腔内,使所述阻尼层与所述轨腔内壁密贴。本发明的这种具有降噪功能的接触轨系统,尤其适用于采用高架形式的新型轨道交通模式,能够有效降低行车中接触轨产生的噪音。
