Multi-layer ring-shaped tuning liquid column damper
Abstract
The utility model relates to a multilayer ring-shaped tuning liquid column damper which comprises a plurality of coaxial cylindrical shells which are stacked from inside to outside but not in contact, the tops of all the cylindrical shells are open and located on the same horizontal plane, the bottoms of all the cylindrical shells are closed and located on different horizontal planes, and every two adjacent cylindrical shells respectively form a cavity; a plurality of L-shaped partition plates which are evenly distributed in the circumferential direction are arranged between every two adjacent cylindrical shells, so that a plurality of communicated sub-cavities are formed in all the cavities, all the L-shaped partition plates are fixedly connected to the cylindrical shells making contact with the L-shaped partition plates, and all the cavities are filled with liquid. Holes with specific opening areas can be formed in the bottom of each partition plate. On the basis of an existing one-way tuning liquid column damper, multi-way vibration reduction and energy dissipation are achieved, the tuning frequency band width can be enlarged so that multi-order vibration modes of a structure can be controlled at the same time, or the mass of liquid in the damper can be increased so that the control efficiency of a certain-order vibration mode can be improved.
