Rail impact damping vibration absorber
The invention relates to a rail impact damping vibration absorber. The absorber comprises an elastic damping body (3), wherein a plurality of motion guide grooves (7) are formed in the elastic dampingbody (3), a gap is formed between each motion guide groove (7) and a rail web face (2) or a rail foot upper face (8), and at least one resonance mass body (5), at least one resonance mass body (5), at least one motion guide groove (7) and an elastic damping body (3) form a vibration combination body (6), and the vibration combination body (6) is closely attached to the rail waist surface (2) or the rail foot upper surface (8). Compared with the prior art, the vibration absorber has advantages of being simple in structure, capable of achieving simultaneous vibration absorption in the verticaldirection and the horizontal direction, good in vibration absorption effect and the like.
本发明涉及一种轨道冲击阻尼吸振器，包括弹性阻尼体(3)，所述的弹性阻尼体(3)内设有多个运动导槽(7)，各运动导槽(7)与轨腰面(2)或与轨脚上面(8)之间构成空隙，该空隙内设有至少一个谐振质量体(5)，谐振质量体(5)、运动导槽(7)和弹性阻尼体(3)组成振动组合体(6)，振动组合体(6)密切贴合在轨腰面(2)或与轨脚上面(8)上。与现有技术相比，本发明具有结构简单、可实现在垂直与水平两个方向的同时吸振、吸振效果好等优点。
