Rail transit near-rail noise reduction device
The invention discloses a rail transit near-rail noise reduction device, which is used for urban rail transit noise reduction and is composed of an elastic clamp and noise reduction bodies. The noisereduction body is installed between sleepers and located in a groove in the outer side of a steel rail, one end of the elastic clamp hooks the inner side of the steel rail, and the other end of the elastic clamp clamps a groove of the noise reduction body. The rail transit near-rail noise reduction device has the advantages of simple structure, stable performance, wider applicable frequency domainrange, long service life, good vibration and noise reduction effect and excellent cost performance; and the device is simple, easy to implement and convenient to operate, can be widely applied to controlling vibration and noise of the steel rail in the rail transit operation process, and has very wide market application prospects.
一种轨道交通近轨降噪装置，用于城市轨道交通降噪，它由弹性卡、降噪体组成；降噪体安装在轨枕之间且位于钢轨外侧的凹槽内，弹性卡一端勾住钢轨内侧，弹性卡另一端卡住降噪体的沟槽。本发明结构简单，性能稳定，适用频域范围更广，使用寿命长，减振降噪效果好，性价比十分优越；简单易行，操作方便，可以广泛应用于控制轨道交通运营过程中钢轨的振动及噪声，其市场应用前景十分广阔。
