Rail transit elastic damping node intrusive vibration suppression device and rail plate structure
The invention relates to a rail transit elastic damping node intrusive vibration suppression device and a rail plate structure, the device comprises a rotating ring and a damping piece, the damping piece is an elastic material component, the damping piece is sleeved in the rotating ring, the rotating ring is connected with a first connecting rod, and the damping piece is connected with a second connecting rod; the change of the included angle between the first connecting rod and the second connecting rod enables the inner side and the outer side of the damping piece to be twisted relatively. One of the first connecting rod and the second connecting rod is connected with the track foundation, the other connecting rod is connected with the track plate, the track plate mainly generates vertical displacement, the damping piece provides elastic force, inhibits vertical displacement of the track plate and reduces amplitude, meanwhile, the vertical displacement drives change of an included angle between the first connecting rod and the second connecting rod, and the damping piece is twisted to generate shear deformation. The damping device generates damping for restraining vibration of the track plate, consumes vibration energy, improves stability of the track plate, is simple in structure, light, convenient to install and good in vibration restraining effect, and the installation position does not affect maintenance and overhaul of a track system.
本发明关于一种轨道交通弹性阻尼节点介入式抑振装置及轨道板结构，该装置包括转环和阻尼件，阻尼件为弹性材料构件，阻尼件套接于转环内，转环连接第一连杆，阻尼件连接第二连杆，第一连杆和第二连杆之间夹角的变化能够使阻尼件的内侧和外侧之间相对扭转。本发明中第一连杆和第二连杆之一连接轨道基础，另一连杆连接轨道板，轨道板主要发生垂向位移，阻尼件提供弹性力，抑制轨道板垂向位移，减小振幅，同时垂向位移带动第一连杆和第二连杆之间夹角的变化，使得阻尼件扭转发生剪切变形，产生抑制轨道板振动的阻尼，并消耗振动能量，提高轨道板的稳定性，该装置结构简单、轻盈，安装方便，抑振效果好，安装位置不影响轨道系统的维护和检修。
