Shape memory alloy self-restoration rubber damper

Abstract

The invention discloses a shape memory alloy self-restoration rubber damper which comprises an upper main plate and a lower main plate paired with the upper main plate. The upper main plate and the lower main plate are symmetrically distributed up and down. The upper main plate is connected with a pair of upper auxiliary plates, and the lower main plate is connected with a pair of lower auxiliary plates. The upper auxiliary plates and the lower auxiliary plates are connected in an inserted mode. Two rubber plates are arranged between the upper auxiliary plates and the lower auxiliary plates. The inner sides of the upper auxiliary plates are provided with a hyperelastic shape memory alloy wire. A pair of drums is separately connected with the left side and the right side of the lower portion of the upper main plate, and a pair of pistons sleeved with the pair of drums is separately connected with the left side and the right side of the upper portion of the lower main plate and reciprocates in the drums. By adoption of the shape memory alloy self-restoration rubber damper, the problems that a building or a structure inclines and collapses due to the fact that dynamic response is caused by earthquake action or a wind load are solved; the shape memory alloy self-restoration rubber damper is simple in structure, convenient to construct, economical, practical and capable of effectively reduce structural dynamic response; self restoration can be achieved, the purpose of reinforcement is achieved, and the resistance capacity of civil engineering under earthquake action and dynamic loads such as the strong wind load is improved; and the shape memory alloy self-restoration rubber damper is high in energy dissipation capacity.

Description

technical field [0001] The invention relates to the technical field of anti-vibration and vibration reduction of civil engineering structures, in particular to a shape-memory alloy self-resetting rubber damper, which is suitable for the energy consumption and vibration reduction requirements of buildings / structures. Background technique [0002] Civil engineering structures will produce large vibrations under external effects such as earthquakes and strong winds, which seriously affect the safety and comfort of the structure. Therefore, how to reasonably and effectively reduce the dynamic response of engineering structures caused by dynamic loads such as earthquakes and strong winds, and improve the earthquake resistance, wind resistance and disaster resistance of engineering structures is one of the problems to be solved urgently in civil engineering. The more traditional method is to increase the stiffness, strength and ductility of the structure, which can reduce the dyna...
