Damper based on self-resetting
The damper comprises a damper body and a first cavity which is formed in one end of the damper body and is of a cylindrical structure, a ball screw mechanism is arranged in the first cavity, and the peripheral side of a rotating block of the ball screw mechanism is coaxially sleeved with an inner cylinder rotating synchronously with the rotating block; a groove-shaped structure extending in the circumferential direction of the inner cylinder is formed in the outer circumferential wall of the inner cylinder, an outer cylinder is coaxially connected to the outer circumferential side of the inner cylinder in a sleeving mode, a check block is connected to the inner circumferential wall of the outer cylinder, a pushing part is arranged at the other end of the groove-shaped structure, and an idle stroke structure for the inner cylinder to idle is arranged between the pushing part and the check block in the circumferential direction of the inner cylinder. An SMA torsion reed is connected between the outer cylinder and the first cavity, short translation displacement of the ball screw can be converted into large rotation displacement of the rotating block, the SMA torsion reed is driven to conduct energy consumption and rapid reset, multi-stage fortification is achieved through a groove-shaped structure and an idle stroke structure, semi-active control is achieved through an electromagnetic inertial device, and the safety of the device is improved. And the seismic response of the structural system is reduced to the maximum extent.
本发明公开一种基于自复位的阻尼器，包括阻尼器本体及开设在其一端且呈筒状结构的第一腔室，第一腔室内设有滚珠丝杠机构，滚珠丝杠机构的转动块的外周侧同轴套接有与其同步转动的内筒，内筒的外周壁上开设有沿其周向延伸的槽状结构，内筒的外周侧同轴套接有外筒，外筒的内周壁上连接有挡块，槽状结构的另一端设有推动部，推动部与挡块沿内筒周向之间设有供内筒空转的空程结构，外筒与第一腔室之间连接有SMA扭转簧片，利用滚珠丝杠通过较短的平动位移可以转换成转动块较大的转动位移，并带动SMA扭转簧片进行耗能和快速复位，且通过槽状结构和空程结构，以此达到多阶段设防，再通过电磁惯质装置实现半主动控制，最大化减小结构体系的地震响应。
