Self-reset high-energy-consumption shape-memory-alloy friction damper
The invention relates to a self-reset high-energy-consumption shape-memory-alloy friction damper. The self-reset high-energy-consumption shape-memory-alloy friction damper comprises an upper ring flange and a lower ring flange, wherein an upper slideway is arranged on the lower surface of the upper ring flange, a lower slideway parallel to the upper slideway is arranged on the upper surface of the lower ring flange, the upper slideway is in sliding connection with at least two upper slide blocks through upper friction pairs, every two adjacent upper slide blocks are connected through an upper shape memory alloy wire, the lower slideway is in sliding connection with lower slide blocks through lower friction pairs, the number of the lower slide blocks is one more than that of the upper slide blocks, any upper slide block is connected with each of the corresponding lower slide blocks below the two sides of the corresponding upper slide block through a connecting rod, the upper and lower ends of the connecting rods are respectively hinged with the upper and lower slide blocks, and limiting members which are located at the two ends of the a lower rail are arranged on the upper surface of the lower ring flange. According to the self-reset high-energy-consumption shape-memory-alloy friction damper, the characteristics that shape memory alloy has self-reset capability and friction elements are high in energy consumption are comprehensively utilized, so that the aims of vertical vibration control and self resetting for engineering structures can be realized.
