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.
