SMA tow self-resetting damper based on ball screw
The invention belongs to the technical field of civil engineering structure damping, and relates to a ball screw-based SMA tow self-resetting damper which comprises a shell, a rotor structure, a stator structure, SMA tows and a ball screw rod, the rotor structure and the stator structure are arranged in the shell, the rotor structure is rotationally arranged in the shell, and the stator structure is rotationally arranged in the shell. The device comprises a ball screw nut and an SMA tow movable end anchoring plate fixedly connected with the ball screw nut. The ball screw rod is inserted into the shell in the axial direction of the shell, and the ball screw nut is arranged on the ball screw rod in a sleeving mode to form a ball screw pair so that linear motion of the ball screw rod can be converted into rotary motion of a rotor structure. The stator structure is fixedly installed in the shell and comprises an SMA tow fixed end anchoring plate and an SMA tow winding column fixedly connected with the SMA tow fixed end anchoring plate, the two ends of each SMA tow are connected with the SMA tow movable end anchoring plate and the SMA tow fixed end anchoring plate respectively, the number of the SMA tows is at least two, the SMA tows are evenly arranged on the SMA tow fixed end anchoring plate in the circumferential direction, and the SMA tow winding column is fixedly connected with the SMA tow movable end anchoring plate. And the SMA tow winding column is arranged along the axial direction of the shell, so that the SMA tow is wound on the SMA tow winding column under the action of rotational motion of the rotor structure.
本发明属于土木工程结构减震技术领域，涉及一种基于滚珠丝杠的SMA丝束自复位阻尼器，包括外壳、安装在外壳内的转子结构和定子结构、SMA丝束以及滚珠丝杠螺杆，所述转子结构转动安装在所述外壳内，其包括滚珠丝杠螺母和与其固定连接的SMA丝束活动端锚固板；所述滚珠丝杠螺杆沿外壳的轴向插入外壳内，且所述滚珠丝杠螺母套设在所述滚珠丝杠螺杆并形成滚珠丝杠副，以将所述滚珠丝杠螺杆的直线运动转换为转子结构的回转运动；所述定子结构固定安装在所述外壳内，其包括SMA丝束固定端锚固板和与其固定连接的SMA丝束缠绕柱，所述SMA丝束的两端分别连接所述SMA丝束活动端锚固板和SMA丝束固定端锚固板，所述SMA丝束至少为2根，并沿圆周方向均匀布置在SMA丝束固定端锚固板上，且所述SMA丝束缠绕柱沿外壳的轴向布置，以使得所述SMA丝束在转子结构回转运动的作用下缠绕在所述SMA丝束缠绕柱上。
