Abstract

This invention relates to the mixed memory alloy damper. It is composed of austenite memory alloy-wire, martensite memory energy consumption alloy spring, left and right drawplate, fixed plate, prestressed adjusted plate, push and pull rod, inner and outer canister. The characteristic of it is as fellows: There are right and left drawplate and fixed plate on the both side of the directed inner canister, and there is prestressed adjusted plate on the outer side of the left drawplate. Form memory energy consumption alloy spring winds on the push and pull rod of the inner canister, and both side of it individually fixed on the left and right drawplate. Four couple of form memory alloy-wire passes through the prestressed adjusted plate, left and right drawplate and fixed plate, and both side are strained and fixed by the clamp. This invention has high energy consumption and automatic replacement, and its structure and form are conveniently applied to the engineering. It can connect to the structure of the high-rise building by the herringbone and oblique backstop, and it also can assemble with other shock isolators to complex shock isolator which is fixed in the structure of shock isolator.

Description

technical field [0001] The invention belongs to the anti-seismic technical field of civil engineering structures, and relates to a hybrid shape memory alloy damper. Background technique [0002] Earthquakes and strong winds pose a serious threat to the safety and comfort of civil engineering structures. How to effectively reduce the response of engineering structures under dynamic loads such as earthquakes and winds, and improve the structures' anti-seismic, wind-resistant and disaster-resistant performances is one of the problems to be solved urgently in the discipline of civil engineering. The traditional anti-seismic strategy is to passively rely on the stiffness, strength and ductility of the structure itself to resist the effects of earthquake and wind vibration. Under the action of strong earthquakes, it will inevitably lead to damage or destruction of some structural components, which is neither economical nor expected. effect, and modern structural vibration control...
