Abstract

The invention relates to an aluminum honeycomb / lead composite energy consumption device. The aluminum honeycomb / lead composite energy consumption device mainly comprises an upper fixed plate, a lower fixed plate, steel gratings, upper and lower filling polymers and aluminum honeycomb / lead composite bodies, wherein the upper fixed plate and the lower fixed plate are flat steel plates; screw holes are formed in four corners of each fixed plate respectively; the strip-shaped steel gratings corresponding to each other are discontinuously and fixedly connected to the opposite surfaces of the upper fixed plate and the lower fixed plate; the distances between the steel gratings are equal; grooves which vertically correspond to each other are formed; both ends of each aluminum honeycomb / lead composite body are embedded into the corresponding grooves which vertically correspond to each other; the polymers are injected into the grooves; after the polymers are solidified, the aluminum honeycomb / lead composite bodies are fixed in the grooves; each aluminum honeycomb / lead composite body is formed by filling each single cell with an aluminum honeycomb core material in a molten state. The aluminum honeycomb / lead composite energy consumption device is simple in structure, low in manufacturing cost, strong in lead restraint and high in composite energy consumption capacity, and has high economical and practical values.

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...
