Damper of suspension nested tuning liquid particles

Abstract

The invention relates to a damper of suspension nested tuning liquid particles. The damper comprises one or a plurality of damper cavity units, buffer materials, a nested particle group and internal liquid. The nested particle group is composed of a plurality of double-layer nested suspension balls, the small balls and the large balls are fixedly connected through springs, and the interiors of the small balls are filled with air and the particles. The small balls suspend by adjusting the proportion of the air and the particles and serve as a relatively-independent damper body. The interiors of the damper cavity units are filled with the liquid, and the inner walls and the bottoms of the damper cavity units are paved with the buffer materials. Under the effect of wind or / and an earthquake, through continuously mutual collision and friction between the particles and the particles in a particle unit, between the particle group and the inner walls of the cavity units and between a particle unit group and the internal liquid and continuous shaking of the liquid, energy of an earthquake is absorbed and dissipated. The suspension state of the particle unit group can improve collision efficiency between the particles and the shocking frequency of the internal liquid, and through introduction of the buffer materials, the damping capacity of the damper can be improved.

Description

technical field [0001] The invention relates to a suspended nested tuned liquid particle damper, in which a particle group composed of a plurality of balls with built-in particles is suspended inside one or more damper units filled with liquid, through the collision between nested particle groups, Friction, spring vibration between large and small balls and continuous sloshing of internal liquid to absorb and dissipate the energy of the earthquake, belongs to the field of vibration control of civil structures (including high-rise buildings, high-rise structures and bridge structures, etc.). Background technique [0002] In recent years, with the rapid development of high-rise buildings, the problems of earthquake vibration and wind-induced vibration have received extensive attention and research. Among them, the particle damper, which realizes momentum exchange and structural energy dissipation through inelastic collision and friction between particles-structures and particl...

Problems solved by technology

[0004] In order to solve the problems of low collision efficiency, low vibration starting point and large noise during operation of the traditional particle damper, the purpose of the present invention is to propose a suspension nested tuned liquid particle damper, which plays the role of the traditional particle damper. Based on the advantages of the damper, it is improved, that is, inside one or more liquid-filled damper cavities, multiple double-layer nested suspension balls are placed, and cushioning materials are added at the same time
