Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a gear-type self-resetting damper based on SMA materials includes a protective sleeve 1, a force transmission steel plate 2, a first toothed steel plate group 3, a second toothed steel plate group 4, a gear 5, a gear plate 6, SMA wire 7, lock nut 8, limit bar 9;

[0032] The protective sleeve 1 is arranged symmetrically with respect to its central axis direction, one end of the protective sleeve 1 along the central axis direction of the protective sleeve 1 has a square hole, and the other end is closed and connected with a welding fixing plate; the protective sleeve 1 has a square hole at one end There is a protruding part, and a hole with the same size as the square hole is provided in the protruding part. The hole guides the force transmission steel plate 2, w...

Abstract

The invention relates to the technical field of civil engineering anti-seismic energy dissipation and disaster prevention and reduction control, in particular to a gear type re-centering damper based on SMA (Shape Memory Alloys) materials. The damper comprises a protection sleeve, a force transmission steel plate, a first steel plate group with gears, a second steel plate group with gears, gears, gear plates, SMA wires, locking screw nuts and position limiting strips. The damper has the advantages that the structure is simple; economical and practical effects are achieved; the performance is reliable; the service life is long; the hyperelastic SMA materials are used; through a great-transmission-ration displacement amplification type mechanical moving system consisting of the force transmission steel plate, the gears and the gear plates, the excellent energy dissipation function and the excellent re-centering function of the damper are realized; the fast response to the to power reaction of a civil and architectural engineering structure provided with the gear type re-centering damper under the seismic effect can be realized; in the dissipation aspect, the partial seismic energy is dissipated by an engineering structure body; and the goal of effectively reducing the engineering structure damage degree is achieved.

Description

technical field [0001] The invention relates to the technical field of energy consumption and vibration reduction and disaster prevention and mitigation control in civil engineering, in particular to a gear-type self-resetting damper based on SMA material. Background technique [0002] Earthquake is a natural disaster that can cause heavy losses to the safety of human life and property, especially as the span of buildings increases and the form of building structures becomes increasingly complex, engineering structures designed by traditional design methods suffer huge damage under the action of strong earthquakes and inevitable economic and property losses. [0003] In the design of anti-seismic engineering structures, it is an effective way to improve the stability and safety of structures by suppressing the dynamic response of the structure body caused by external dynamic loads through vibration control technology. Vibration control technology is to install energy-dissip...
