Abstract

The invention relates to an aluminum honeycomb / lead composite energy consumer, which mainly includes upper and lower fixing plates, steel grids, upper and lower filling polymers, and an aluminum honeycomb / lead composite body. Among them, the upper and lower fixing plates are steel flat plates with screw holes on the four corners, and the corresponding bar-shaped steel grids are intermittently fixed on the opposite surfaces of the upper and lower fixing plates. The distance is equal to form corresponding grooves up and down, and the two ends of the aluminum honeycomb / lead composite are embedded in the corresponding grooves up and down, and then polymer is injected into the groove, and the aluminum honeycomb / lead composite is fixed when the polymer is cured In the groove; the aluminum honeycomb / lead composite is formed by filling each single cell of the aluminum honeycomb core material with molten lead. The invention has the advantages of simple structure, low production cost, strong restraint on lead, strong composite energy consumption capacity, and high economic and practical value.

Description

technical field [0001] The invention relates to an energy dissipation component for building structure and large-scale mechanical vibration control. Background technique [0002] Metal yield energy dissipators are various forms of energy dissipating components made of mild steel or other soft metal materials, which are a type of elastic-plastic energy dissipators. Metals have good hysteretic performance after yielding, and use the elastic-plastic hysteretic deformation energy dissipation of some metals, including mild steel energy dissipators, lead energy dissipators, etc. [0003] The lead energy dissipator makes full use of the characteristics of lead, such as low melting point, good plasticity, low strength, strong corrosion resistance, and strong lubricating ability. At the same time, due to its high ductility and flexibility, it can absorb a large amount of energy during deformation, and It has strong deformation tracking ability, and through dynamic recovery and recry...
