Subway floating slab broadband shock absorber based on particle damping
The invention discloses a metro floating slab broadband shock absorber based on particle damping. The metro floating slab broadband shock absorber comprises an outer sleeve, an inner sleeve, a top plate, a particle damping device, a base plate, a piston, a steel spring, a base and the like. The outer sleeve is connected with the floating slab through the pre-embedded ribs, and other components are protected in the outer sleeve. The particle damping device is installed above the inner sleeve, when the steel spring in the inner sleeve vibrates, particles in the particle damping device move along with the steel spring, collision, friction, sliding or rolling can happen in the movement process to dissipate energy, and therefore the vibration reduction effect is achieved. Particle damping is added and matched with the steel spring, the vibration reduction frequency is wider, and the problem that an existing steel spring floating slab is not ideal in low-frequency vibration reduction effect can be solved.
本发明公开了一种基于颗粒阻尼的地铁浮置板宽频减振器，所述减振器包括外套筒、内套筒、顶板、颗粒阻尼装置、垫板、活塞、钢弹簧、底座等；所述外套筒通过预埋筋与浮置板连接，将其它构件保护在内；所述颗粒阻尼装置安装在内套筒上方，当内套筒中的钢弹簧振动，装置中的颗粒也随之运动，运动过程中会发生碰撞、摩擦、滑动或滚动来耗散能量，从而实现减振效果。加入颗粒阻尼，与钢弹簧互相配合，减振频率更宽，能改善现有钢弹簧浮置板对低频振动减振效果不理想的问题。
