Abstract

High complex absorber which is used in civil engineering structure absorption of vibration. The interior and exterior steel pipe surrounded by the absorber consists of three parts, the central cavity is liquid amortisseur, and the side cavitys are lead amortisseur. On the left of the interior steel pipe, there fixes a board, on the right is the controlling board. On the left of the exterior steel pipe is fixed the inner board, on the right there respectively fixes the left and right ellipsoidal bulges between the left cavity baffle plate and the interior steel pipe and on the interior steel pip between the right baffle plate and the inner sealed plate. On the ellipsoidal bulges there is exterior perfusion lead, there are sealing port and pouring port in the central exterior wall of the exterior steel pipe, on the interior steel pipe is welded a moving valve in which there is a liquor tube and between the left cavity baffle plate and right cavity baffle plate is he perfusion liquor.

Description

technical field

[0001] The invention is an anti-vibration (shock) device for civil engineering structures, in particular a composite shock absorber. Background technique

[0002] Earthquake force and wind vibration force are the main control loads borne by the building structure, and are also the main factors leading to the damage and collapse of the building structure. Accurately understand the force mechanism and dynamic response of the structure under the action of dynamic load, and implement reliable measures for it. Anti-vibration (earthquake) protection measures are a frontier research topic. Structural energy dissipation and vibration reduction control is a new type of anti-vibration (seismic) method, that is, using energy dissipation and vibration reduction devices to consume external excitation energy, so as to reduce the damage of external excitation to the main structure. At present, energy-dissipating vibration damping devices developed and researched for wind v...
