Floating slab track structure based on particle damper
The invention relates to a floating slab track structure based on a particle damper, the floating slab track structure is arranged above a roadbed, the floating slab track structure comprises steel rails, a floating slab and the particle damper, the two steel rails are symmetrically arranged above the floating slab, the lower portion of the floating slab is connected with the roadbed through a vibration isolator, and the particle damper is arranged below the floating slab. Particle dampers are symmetrically arranged in the middle or on the two sides of the floating slab, each particle damper comprises a damper cavity and damping particles, the damping particles are arranged in the damper cavities, and the damping particles are used for widening the frequency range and isolating vibration energy. Compared with the prior art, by adding the damping particles, on the basis that the vibration isolation effect of the floating slab is guaranteed, the more excellent track structure damping performance is achieved.
本发明涉及一种基于粒子阻尼器的浮置板轨道结构，所述浮置板轨道结构设于路基上方，所述浮置板轨道结构包括钢轨、浮置板和粒子阻尼器，所述浮置板上方对称设有两根钢轨，所述浮置板下方通过隔振器与路基相接，所述浮置板中间位置或两侧对称设有粒子阻尼器，所述粒子阻尼器包括阻尼器腔体和阻尼粒子，所述阻尼器腔体内设有阻尼粒子，所述阻尼粒子用于拓宽频率范围，隔离振动能量。与现有技术相比，本发明通过增加阻尼粒子，在保证浮置板隔振效果的基础上，达到更加优异的轨道结构阻尼性能。
