Multidirectional hydraulic vibration reduction dynamic vibration absorber structure of steel rail
The invention belongs to the technical field of vibration and noise reduction of rail transit and discloses a multidirectional hydraulic vibration reduction dynamic vibration absorber structure of a steel rail. The structure is arranged on two sides of a rail web of the steel rail. An elastic damping body is included. The elastic damping body is tightly attached and fixed to the steel rail, one ormore hydraulic vibrators are evenly embedded in the elastic damping body at intervals, each hydraulic vibrator comprises an even number of hydraulic telescopic rods, every two hydraulic telescopic rods are collinearly and oppositely connected together to form a spherical array structure, each hydraulic telescopic rod can be divided into a piston rod and a piston cylinder, and damping oil is arranged in each hydraulic telescopic rod. Vibration energy is consumed through telescopic movement of the hydraulic telescopic rod, a vertical vibration reduction effect can be achieved on a straight section of a railway, a transverse and vertical bidirectional vibration reduction effect can be realized on a curve section of the railway, and meanwhile an auxiliary anti-bending and anti-torsion effectcan be achieved.
本发明属于轨道交通减振降噪的技术领域，公开了一种钢轨的多向液压减振动力吸振器结构，设置在钢轨的轨腰两侧，包括弹性阻尼体，所述弹性阻尼体紧贴固定在钢轨上，其内部均匀间隔嵌装有一个或者多个液压振子，所述液压振子包括偶数个液压伸缩杆，它们两两共线相向相连到一起，组成球形阵列结构，该液压伸缩杆可分为活塞杆和活塞筒，内部设置有阻尼油。本发明通过液压伸缩杆的伸缩运动将振动能量消耗掉，不仅可以在铁路的平直段起到垂向减振的作用，还能在铁路的弯道段起到横垂双向减振的作用，同时还可以起到辅助抗弯扭的作用。
