Abstract

The invention relates to an ultralow-frequency tuned mass inertial damper, and relates to the technical field of damping vibration attenuation devices, the ultralow-frequency tuned mass inertial damper comprises a fixed box and a damper body arranged in the fixed box, the damper body comprises a spring, a damping piece, a mass block and an inertial container, and one end of the spring and one end of the damping piece are fixed to the top of the fixed box; the mass block is fixedly connected with the other end of the spring and the other end of the damping piece and rotationally connected with a rotating shaft. The inerter comprises a rack, a flywheel and a gear, the rack is vertically fixed in the fixed box, the flywheel is fixedly sleeved at one end of the rotating shaft, the gear is fixedly sleeved at one end, close to the flywheel, of the rotating shaft, and the gear is located on the side of the rack and can be meshed with the rack; the mass block can be driven by the spring to move up and down and can drive the flywheel and the gear to move up and down through the rotating shaft, and the gear can be meshed with the rack and drive the flywheel to rotate around the rotating shaft while moving up and down. The static elongation of the spring can be reduced, the frequency and the initial friction resistance can be reduced, and ultralow-frequency structure vibration reduction is achieved.

Description

technical field [0001] The present application relates to the technical field of damping and vibration reduction devices, in particular to an ultra-low frequency tuning mass inertial damper. Background technique [0002] For some buildings and bridge structures where direct dampers cannot be installed by grounding, a tuned mass damper (Tuned Mass Damper, TMD) can usually be installed at the position where the structure has the largest amplitude, and through frequency tuning, the vibration of the structure The large vibration of the mass block in the TMD is caused, and then the vibration energy of the structure is transferred to the damper, and then the energy is dissipated by the damping energy dissipation device inside the damper, and finally the vibration control effect of the structure is realized. Engineering practice has proved that the use of TMD can effectively control the vibration of the structure, which is an effective vibration reduction measure. [0003] However...
