Multi-step steel rail particle shock absorber
The invention discloses a multi-step steel rail particle shock absorber comprising a buckle, a clamping and fixing space and a particle vibration absorber. The buckle wrapping the bottom face of the rail is of a U-shaped structure and is matched with the arc faces of the two sides of the rail to form a clamping and fixing space. The particle vibration absorber is arranged in the clamping and fixing space; the particle vibration absorber comprises a shell, a vertical support, a horizontal support and particle mass blocks, the shell is attached to the arc faces of the two sides of the rail and the inner side wall of the buckle, the vertical support is vertically arranged in the shell, the horizontal support is horizontally arranged on the vertical support, and the particle mass blocks are symmetrically installed at the two ends of the horizontal support. By means of the mode, according to the multi-stage steel rail particle shock absorber, the shock absorber with the multi-stage frequency function is adopted for rail system wide-frequency-band and multi-frequency-band vibration and noise caused by different working conditions of a vehicle, various working conditions are effectively dealt with, and rail system vibration and noise are effectively reduced.
本发明公开一种多阶钢轨颗粒减振器，包括卡扣、卡固空间、颗粒吸振器，包覆在铁轨底面的卡扣呈U型结构且与铁轨的双侧弧面相配合形成卡固空间，所述卡固空间内设置有颗粒吸振器，所述颗粒吸振器包括外壳、竖向支架、水平支架以及颗粒质量块，所述外壳分别与铁轨的双侧弧面、卡扣的内侧壁相贴合，所述外壳内竖直设置有竖向支架，所述竖向支架上水平设置有水平支架，所述水平支架的两端对称安装有颗粒质量块。通过上述方式，本发明提供一种多阶钢轨颗粒减振器，针对车辆不同工况引起的轨道系统宽频段、多频段的振动及其噪声，采用具有多阶频率功能的减振器，有效应对多种工况，有效降低轨道系统振动及噪声。
