Ballastless track steel rail vibration damping device
The invention belongs to a vibration damping device, and particularly relates to a ballastless track steel rail vibration damping device which comprises a bottom plate and a vibration transmitting plate used for being matched with the bottom of a steel rail, wherein a damping layer is arranged between the vibration transmitting plate and the bottom plate, the vibration transmitting plate is opposite to the bottom plate, a resonance piece is arranged on the surface, which is matched with the damping layer, of the vibration transmitting plate, and the resonance piece is arranged in the damping layer in a penetrating mode. According to the invention, the lower end of the damping layer can be restrained so as to restrain the amplitude of the steel rail and dissipate the vibration energy of the steel rail and the vibration energy of the noise reduction damper steel plate, the shearing area and shearing deformation of the damping layer are increased, the vibration energy of the steel rail can be converted into heat energy to the maximum extent, and the vibration reduction and noise reduction effects are improved. The damping layer is restrained to carry out primary vibration suppression and vibration absorption, meanwhile, the transmitted amplitude triggers a resonance piece cantilever vibration, then secondary vibration suppression and vibration absorption are carried out through the resonance piece and the damping layer, and the vibration suppression and vibration absorption effects are better.
本发明属于一种减振装置，具体是涉及到一种无砟轨道钢轨减振装置，底板和用于与钢轨轨底配合的递振板，所述递振板和底板之间设置有阻尼层，所述递振板与底板相对、且与阻尼层配合的一面上设有共振片，所述共振片穿设在阻尼层中；本发明可对阻尼层下端形成了约束，以抑制钢轨振幅并耗散钢轨振动能量和降噪阻尼器钢板振动能量，增大了阻尼层的剪切面积和剪切变形，使得钢轨振动能量能够最大限度地转化为热能，提高减振降噪效果。通过约束阻尼层本身进行一重抑振和吸振，同时传递的振幅引发共振片悬臂振动，再通过共振片和阻尼层进行二重抑振和吸振，使得抑振和吸振效果更好。
