Multilayer circular ring-shaped tuned liquid column damper
Abstract
The invention relates to a multilayer circular ring-shaped tuned liquid column damper. The multilayer circular ring-shaped tuned liquid column damper comprises a plurality of coaxial cylindrical shells which are stacked from inside to outside but are not in contact with one another, wherein the tops of the cylindrical shells are open and are positioned on the same horizontal plane; the bottoms of the cylindrical shells are closed and are positioned on different horizontal planes; each two adjacent cylindrical shells form a cavity respectively; a plurality of L-shaped partition plates which are uniformly distributed circumferentially are respectively arranged between each two adjacent cylindrical shells, so that a plurality of sub-cavities which communicate with one another are respectively formed in the cavities; the L-shaped partition plates are fixedly connected to the cylindrical shells which are in contact with the L-shaped partition plates; the cavities are filled with liquid respectively; and holes with specific opening areas can be formed in the bottoms of the partition plates. On the basis of the existing one-way tuned liquid column damper, multi-way vibration reduction and energy dissipation are realized, the tuned frequency band width can be increased, and meanwhile, the multi-order vibration mode of the structure is controlled, or the quality of the liquid in the damper is improved, so that the control efficiency of a certain order of vibration mode is improved.
