Title:
INERTIAL MASS AMPLIFICATION TUNED MASS DAMPER
Document Type and Number:
WIPO Patent Application WO/2021/051373
Kind Code:
A1
Abstract:
Disclosed in the present invention is an inertia mass amplification tuned mass damper, belonging to the technical field of structural vibration control. The inertial mass amplification tuned mass damper comprises a hollow box body, an I-shaped mass block, gears a, gears b, rectangular frames, steel rings, viscous dampers, a steel sheet, springs, rotating shafts and balls. In the present invention, inertial damping force is amplified by adjusting the ratio of the radii of the gears a and the gears b, and the damping parameters are easily changed by adjusting the mass of the mass block, the stiffness of the springs, etc. The present invention has the advantage of a small designed mass, avoiding the adverse effect on the structure caused by excessive additional gravity, and improving the performance of the structure. The present invention has a reasonable design, occupies a small space, and can save more usage areas for buildings, greatly improving the utilization efficiency of buildings; and has a simple construction, is easy to install, and has a wide application prospect and development potential.
