SMA self-resetting torsion energy dissipation supporting component
The invention relates to an SMA (Shape Memory Alloy) self-resetting torsion energy dissipation supporting member, which belongs to the field of energy dissipation and shock absorption, and comprises an outer sleeve and an inner sleeve which are mutually sleeved, a torsion steel pipe and a torsion self-resetting SMA are alternately arranged in the inner sleeve, and rotating discs are fixed at two ends of the torsion steel pipe and the torsion self-resetting SMA; an upper core plate and a lower core plate which are connected in a sliding mode and used in cooperation with the rotating disc are arranged on a sleeve body of the inner sleeve, supporting connecting pieces are fixed to the upper core plate and the lower core plate, a pair of curve channels are formed in the rotating disc in a central symmetry mode, and supporting columns used in cooperation with the curve channels are arranged on the upper core plate and the lower core plate. When the supporting columns move oppositely or oppositely, the rotating disc rotates, pure torsion is generated in the torsion steel pipe and the torsion self-resetting SMA which are fixedly connected with the rotating disc, energy is dissipated through metal deformation of the torsion steel pipe and the torsion effect of the torsion self-resetting SMA, and meanwhile the torsion self-resetting SMA has the self-resetting capacity and is diverse in energy dissipation mode and good in energy dissipation and vibration reduction effect.
本发明涉及一种SMA自复位扭转耗能支撑构件，属于耗能减震领域，包括相互套接的外套筒和内套筒，内套筒内交替设置有扭转钢管和扭转自复位SMA，扭转钢管和扭转自复位SMA的两端均固定有旋转圆盘，内套筒筒身上设置有滑动连接且均与旋转圆盘相配合使用的上下芯板，上下芯板均固定有支撑连接件，旋转圆盘中心对称开设有一对曲线槽道，上下芯板上均设置有与曲线槽道配合使用的支柱，受到震动时，上下芯板相向或相背运动，支柱也相向或相背运动，使旋转圆盘产生转动，与旋转圆盘固定连接的扭转钢管和扭转自复位SMA内部产生纯扭转，扭转钢管的金属变形及扭转自复位SMA扭转作用耗散能量，同时扭转自复位SMA具备自复位能力，耗能方式多样，耗能减振效果好。
