Track vibration and noise reduction device based on particle damping, damping vibration reduction design method and application
The invention provides a track vibration and noise reduction device based on particle damping, a damping vibration reduction design method and application, the track vibration and noise reduction device comprises two tracks laid in parallel and a plurality of sleepers arranged below the tracks at intervals, the opposite sides of the two tracks are the inner sides, the opposite sides of the two tracks are the outer sides, and the inner sides of the two tracks are the outer sides. A plurality of main vibration reduction boxes are tightly attached to the inner side of the track; the interior of the main vibration reduction box is divided into a plurality of independent filling cavities, the filling cavities are filled with damping particles, the particle sizes of the damping particles filled in the same filling cavity are the same, and the particle sizes of the damping particles filled in at least part of the filling cavities are different from the particle sizes of the damping particles filled in other filling cavities. The mounting partition plates are arranged in the main vibration reduction boxes, reasonable particle filling layout is arranged, damping particles are filled in the main vibration reduction boxes while the mechanical strength is not reduced, a certain vibration reduction effect can be achieved in the vertical direction and the transverse direction of the track structure, and the vibration reduction effect is maximized.
本发明提供了一种基于颗粒阻尼的轨道减振降噪装置、阻尼减振设计方法及用途，包括并行铺设的两条轨道以及间隔设置于所述轨道下方的若干轨枕，两条轨道相对的一侧为内侧，两条轨道相背的一侧为外侧，所述轨道的内侧紧贴设置有若干主减振盒；所述主减振盒的内部分隔形成若干独立的填充腔，所述填充腔内填充有阻尼颗粒，同一所述填充腔内填充的阻尼颗粒的粒径相同，至少部分所述填充腔内填充的阻尼颗粒的粒径与其它所述填充腔内填充的阻尼颗粒的粒径不同。本发明在主减振盒内部均设置安装隔板，设置合理颗粒填充布局，在不降低机械强度的同时内部填充阻尼颗粒，对轨道结构的垂向和横向均能起到一定的减振作用，实现减振效果最大化。
