Problems solved by technology

At present, many shock-absorbing dampers based on SMA materials have been developed, but because SMA wires can only exert their characteristics under tension, many shock-absorbing dampers based on SMA materials have complex structures, difficult parts connection, and high manufacturing costs.

Embodiment Construction

[0021] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0022] A shape memory alloy wire damper based on self-locking thread, such as figure 1 , figure 2 with image 3 As shown, a nut connecting section 1 is included. The nut connecting section 1 includes a screw 1-3. The thread on the screw 1-3 is a self-locking thread. One end of the screw 1-3 is fixedly connected with a hexagonal prism mounting section 1- 2. The prismatic installation section 1-2 is fixedly connected with an upload force column 1-1, which is installed coaxially with the screw 1-3.

[0023] Such as figure 1 , figure 2 , Figure 4 with Figure 5 As shown, a shape memory alloy wire damper based on self-locking threads further includes a screw groove connecting section 2. The screw groove connecting section 2 includes a cylindrical screw groove body 2-3, and the screw groove body 2-3 and The opposite end of the opening is fixedly connected with the...

Abstract

The invention discloses a shape memory alloy wire damper based on a self-locking thread. The damper comprises a nut connection section and a screw groove connection section in threaded sleeve connection, multiple circles of shape memory alloy wires wind around the screw groove connection section and are in pre-tensioned state. The shape memory alloy wire damper based on the self-locking thread issimple in structure, the shape memory alloy wires are in the pre-tensioned state, and tension of the shape memory alloy wires can be increased when axial tension or axial tension is produced under theaction of external force, so that the good damping effect can be realized.

Description

Technical field [0001] The invention belongs to the technical field of shock absorption and energy dissipation devices, and relates to a shape memory alloy wire damper based on a self-locking thread. Background technique [0002] Earthquakes have brought various degrees of harm to human society. Under the action of earthquakes, buildings will be damaged to different degrees. In order to effectively reduce the loss caused by earthquake damage, structural vibration control technology has been fully emphasized and developed. By installing shock-absorbing dampers in specific parts of the building, the dynamic characteristics of the structure or the seismic effect can be changed. [0003] Shape memory alloy (SMA for short) has strong phase change pseudo-elasticity, that is, under the action of external force, shape memory alloy has a much larger deformation recovery capacity than ordinary metals, that is, the large strain generated during the loading process will Restore with uninstall...
