Modularized steel rail particle damper for vibration and noise reduction of rail transit

Abstract

The utility model discloses a modularized steel rail particle damper used for vibration and noise reduction of rail transit. The modularized steel rail particle damper is used for being arranged at the rail web position. The particle damper comprises a plurality of target vibration reduction modules, a plurality of target vibration reduction modules and a plurality of target vibration reduction modules, and the connecting piece is detachably connected with the multiple target vibration reduction modules. The target vibration reduction modules are connected through the connecting pieces to form the particle damper, a wide vibration reduction frequency range can be formed by adopting the different vibration reduction modules, and therefore the particle damper is suitable for reducing broadband noise generated in the steel rail operation environment. 本实用新型公开了一种用于轨道交通减振降噪的模块化钢轨颗粒阻尼器，用于设置于轨腰位置的轨腰位置；所述颗粒阻尼器包括：目标减振模块，所述减振模块有若干个；以及连接件，所述连接件可拆卸连接若干个所述目标减振模块。通过连接件连接各目标减振模块，形成颗粒阻尼器，采用不同的减振模块可以形成较宽的减振频率范围，从而适用于降低钢轨运行环境中产生的宽带噪声。
