Track vibration reduction fastener with high transverse stability and rigidity changing method thereof
The invention belongs to the technical field of rail damping, and particularly discloses a rail damping fastener with high transverse stability, which comprises a rail damper arranged at the lower end of a steel rail and a sleeper positioned below the rail damper, and the rail damper is of an integrated metal-rubber composite structure. The rail shock absorber comprises a metal top plate, a metal bottom plate and a rubber vulcanization body, the metal top plate, the rubber vulcanization body and the metal bottom plate comprise a first inverted-cone-shaped side wall, an inverted-cone-shaped rubber vibration isolation peripheral wall and a second inverted-cone-shaped side wall which are matched with one another from inside to outside, and a bottom support is arranged between the rail shock absorber and the sleeper. The rail shock absorber has high transverse stability while having good shock absorption performance, and meanwhile, the non-linear variable rigidity and protection rigidity can be achieved through the rail shock absorber.
本发明属于轨道减振技术领域，具体公开了一种高横向稳定性的轨道减振扣件，包括设于钢轨下端的轨道减振器和位于轨道减振器下方的轨枕，轨道减振器为一体式的金属‑橡胶复合结构，轨道减振器包括金属顶板、金属底板和橡胶硫化体，金属顶板、橡胶硫化体和金属底板包括从内向外相互匹配的倒锥形侧壁一、倒锥形橡胶隔振周壁和倒锥形侧壁二，轨道减振器和轨枕之间设有底支座。本发明可在具有良好减振性能的同时具备较高的横向稳定性，同时轨道减振器可实现非线性变刚度及保护刚度。
