Rigidity damping intrusive vibration suppression device
The invention relates to a rigidity damping intervention type vibration suppression device which comprises a plurality of upper toothed plates and a plurality of lower toothed plates, the upper toothed plates are arranged at intervals in the length direction of a steel rail and connected to the bottom face of the rail bottom of the steel rail, the lower toothed plates are connected to the top face of a bottom plate, and the upper toothed plates and the lower toothed plates are arranged in a staggered mode. A deformation block is connected between the adjacent side wall of the upper toothed plate and the side wall of the lower toothed plate and is an elastic material component, gaps are formed between the top face of the lower toothed plate and the bottom face of the steel rail and between the top face of the deformation block and the bottom face of the steel rail, gaps are formed between the bottom face of the upper toothed plate and the bottom face of the deformation block and the top face of the bottom plate, and the gaps meet the shearing deformation space of the deformation block. The bottom plate is used for being connected to a rail bearing component. When a train passes, the steel rail generates vertical and transverse displacement, so that the upper toothed plate and the lower toothed plate generate relative shearing dislocation in the vertical direction or the transverse direction, in the process, the deformation block is driven by dislocation of the upper toothed plate and the lower toothed plate, shearing deformation occurs, damping for restraining vibration of the steel rail is generated, vibration energy is consumed, and therefore the stability of the steel rail is improved.
本发明关于一种刚度阻尼介入式抑振装置，包括若干个上齿板和若干个下齿板，上齿板沿钢轨的长度方向间隔设置，且连接于钢轨轨底的底面，下齿板连接于底板顶面，上齿板和下齿板交错设置，相邻的上齿板侧壁和下齿板侧壁之间连接有变形块，变形块为弹性材料构件，下齿板顶面和变形块顶面分别与钢轨底面之间具有间隙，上齿板底面和变形块底面分别与底板顶面之间具有间隙，间隙满足变形块的剪切变形空间，底板用于连接于承轨部件。列车通过时，钢轨发生垂向和横向位移，使得上齿板和下齿板在竖向或横向相互之间发生相对剪切错动，过程中变形块受到上齿板和下齿板错位带动，发生剪切变形，产生抑制钢轨振动的阻尼，并消耗振动能量，从而提高钢轨的稳定性。
