The invention provides a threaded sleeve type stretching friction energy dissipater and a using method. The energy dissipater is formed by assembling two cylindrical sleeves, a cylindrical friction screw, two anti-rotation torsional springs and two limiting screws. A section of friction inner thread and a section of sleeve tail inner thread are arranged at the two ends of the inner wall of each sleeve respectively, and a plurality of rotation-resisting screw holes are further formed in the sleeve wall of each sleeve. Two sections of friction outer threads and two sections of sleeve spring thin sections are symmetrically arranged on a rod body of the friction screw, and a rod body small hole is formed in each section of sleeve spring thin section. The sleeves and the friction screw are connected through mutual meshing of the friction inner threads and the friction outer threads. The anti-rotation torsional springs are connected to the sleeve spring thin sections in a sleeving mode, and the two ends of each anti-rotation torsional spring are fixed to the corresponding rod body small hole and a corresponding sleeve wall small hole respectively. When the two ends of the energy dissipater are subjected to large pulling force, energy dissipation can be achieved through relative rotation friction resistance between the friction outer threads and the friction inner threads, and automatic resetting is completed through restoring force of the anti-rotation torsional springs. The threaded sleeve type stretching friction energy dissipater is simple in structure, easy and convenient to control, capable of achieving pulled one-way friction energy dissipation and automatic resetting, convenient to apply and wide in application range.
一种螺纹套筒式拉伸摩擦耗能器及使用方法，耗能器由两个圆筒形套筒、一个圆柱形摩擦螺杆、两个抗旋扭簧、两个限位螺钉组装而成。套筒内壁两端分别设有一段摩擦内丝和一段筒尾内丝，套筒筒壁还设有若干个阻旋螺孔。摩擦螺杆杆身对称设有两段摩擦外丝和两段套簧细段，每段套簧细段上设有一个杆身小孔。套筒与摩擦螺杆通过摩擦内丝与摩擦外丝的相互啮合实现连接；抗旋扭簧套接到套簧细段上并将其两端分别固定在杆身小孔和筒壁小孔上。当耗能器两端受到较大拉力时，可依靠摩擦外丝与摩擦内丝之间的相对旋转摩擦阻力实现耗能，自动复位则由抗旋扭簧的恢复力完成。本发明构造简单、控制简便、能够实现受拉单向摩擦耗能和自动复位、应用方便、应用面广。
