Problems solved by technology

At present, there are some dampers developed by using the superelasticity of shape memory alloys, which are mainly divided into two categories according to their functions: one is the energy-dissipating damper, which provides a full hysteresis curve and can co

Embodiment Construction

[0019] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0020] In Fig. 1, the center line and the bottom respectively show the central axis symmetric structure of the damper, in which the arrangement of the guide rod 8 and the energy-dissipating shape memory alloy wire 14 corresponds to the hole position of the corresponding steel plate. The installation process is carried out from inside to outside, and the specific implementation steps are as follows:

[0021] step 1

[0022] According to the requirements of vibration control, determine the material, size and quantity of each component of the damper.

[0023] step 2

[0024] The left inner steel plate 2 and the right inner steel plate 3 are sheathed on the guide rod 8, and are fixed on the pull rod 6 to form a sliding frame, and a sleeve 9 is arranged therebetween to limit the position. The left outer steel plate 1 ...

Abstract

Energy-consumption-resetting shape memory alloy damper is a damping control device used in the areas of civil construction and mechanical engineering technique. Its outer steel plate ,along with the coupling bar ,is sticked into the guide bar and constitutes a rigid fixing structure .The inside steel plate is sticked into the pull-bar of the section , spacing by a sleeve, constituting as a slide frame. The machine works by adjusting screw and nut to exert pre-strain to the centre point of the super elasticity surface plate, with one pair of wires connect the left outer steel plate to the right inside steel plate ,the other pair connect the right outer steel plate to the left inside steel plate. When the sliding frame mount runs,wires in one side are elongated while wires in the other side being buckled,a bigger anamorphosis restoration ability being created. At the same time, two pairs of wires pull and push interchange, which provides a bigger energy consumption and steady damp force. This invention simultaneously has the functions of good energy consumption and resetting.It can reduce the vibration of fabrics and components or the remained deformation.and also has simple structure and easily installed.

Description

technical field [0001] The invention belongs to the technical field of civil engineering and mechanical engineering, and relates to a vibration reduction control device, in particular to a damper with vibration energy consumption and reset functions. Background technique [0002] Shape memory alloy is a new type of functional material with both sensing and driving capabilities, and has special shape memory effect and superelastic effect. Compared with dampers made of other materials, dampers made of shape memory alloys have the advantages of large recoverable deformation, strong damping capacity, durability, corrosion resistance, fatigue resistance, and low maintenance costs. [0003] In structural applications, the evaluation of the excellent performance of the damper is mainly reflected in two aspects: one is the reduction of vibration of the structure or component under dynamic load; the other is the reduction of the residual deformation of the structure or component afte...
