Description
Technical field
The utility model belongs to civil engineering structure anti-seismic technology field, relates to a kind of structure of mixed memory alloy damper.
Background technology
The effect of earthquake, high wind has constituted serious threat for the safety and the comfortableness of civil engineering structure.How to alleviate the response of engineering structures under dynamic loadings such as earthquake and wind effectively, improving antidetonation, the wind loading rating of structure and combating a natural disaster performance is one of problem demanding prompt solution in the civil engineering subject.Traditional antidetonation strategy is that the rigidity, intensity and the ductility that rely on structure self is passively resisted the effect that earthquake motion and wind shake, under severe earthquake action, the damage or the destruction that must cause the structure division member, so not only uneconomical but also do not reach expected effect, and the modern structure vibration control technology is for the rational and effective approach that provides is provided.
The damping technology of passive energy-consumption damper is relatively ripe, yet as a kind of passive control device, durability and corrosion resistance are ubiquitous problems in the present energy consumer.Easily aging as viscoelastic damper, the maintenance of viscous damper, the reliability of frcition damper when long-term use the, the plasticity permanent set of mild steel damper etc.Marmem is a kind of new function material, has peculiar shape memory effect, super-elasticity and high damping characteristic.Utilize the super-elasticity of marmem and the passive energy-consumption damper of high damping characteristic making can overcome the problems referred to above.Advantages such as this class damper is compared with other dampers, has durability and corrosion resistance and good, and life cycle is long, and distortion is big and can recover.But existing marmem damper mainly utilizes the damping characteristic of austenite shape memory alloy, energy dissipation capacity is low, and the damping capacity of martensite marmem is higher than austenite shape memory alloy, and the mixed type damper that utilizes austenitic super-elasticity runback potential energy power and martensitic high damping characteristic to form has greatly improved the control effect.
The utility model content
The utility model provides a kind of mixed memory alloy damper, its objective is to solve the existing low problem of marmem damper energy dissipation capacity, provide a kind of energy dissipation capacity strong, have simultaneously from reset function, form of structure is simple, is convenient to the passive energy-consumption damper that engineering is used.
The technical solution of the utility model is as follows:
This kind mixed memory alloy damper is made up of urceolus 1, inner core 2, martensite shape memory alloy energy-consuming springs 3, Zola's plate 4, right pulling plate 5, austenite shape memory alloy silk 6, fixed head 7, prestressed adjusted plate 8, adjustment screw 9, anchor clamps 10, hold-down screw 11, pull bar 12, protecgulum 13, bonnet 14 and connector 15.It is characterized in that: the guiding inner core 2 two ends be provided with Zola's plate 4, right pulling plate 5 and fixed head 7 respectively, the arranged outside of Zola's plate 4 prestressed adjusted plate 8; Shape memory alloy energy-consuming springs 3 is wrapped on the pull bar 12 in the inner core 2, and two ends are individually fixed in Zola's plate 4 and right pulling plate 5; Four groups of shape-memory alloy wires 6 pass hole 17, the hole 19 on Zola's plate 4, the hole 20 on the fixed head 7 and the hole 22 on the right pulling plate 5 on the prestressed adjusted plate 8, and two ends are strained and fixed with anchor clamps 10 respectively; Four adjustment screw 9 are regulated the initial strain of shape-memory alloy wire 6 by changing the distance between prestressed adjusted plate 8 and the Zola's plate 4 with this; Fixed head 7 and inner core 2 welding are connected with urceolus 1 by hold-down screw 11 then; Protecgulum 13, bonnet 14 and connector 15 link together by bolt or welding manner and urceolus 1; Structural element such as the beam on pull bar 12 and top, damper present position or plate are connected, and connector 15 is connected with the support or the bean column node of bottom, damper present position.
Before the assembling, can require to regulate the initial strain of shape-memory alloy wire 6 according to actual building structure by adjustment screw 9.When pull bar 12 and connector 15 had relative displacement, pull bar 12 drove arm-tie 4 (or 5) motion because of the external force effect, and other end arm-tie 5 (or 4) is stopped by the inner core end, thereby shape-memory alloy wire 6 and shape memory alloy energy-consuming springs 3 are stretched.After external force is removed,, the super-elasticity of shape-memory alloy wire 6 replys also pressurized recovery of shape memory alloy energy-consuming springs 3 simultaneously because driving arm-tie 4 (or 5).Shape-memory alloy wire 6 and shape memory alloy energy-consuming springs 3 have consumed energy in reciprocal stretching and recovery process, reach the purpose of vibration damping.
Effect of the present utility model and benefit are mainly reflected in mixed memory alloy damper and adopt martensite shape memory alloy energy-consuming springs and super-elastic shape memory alloy wire as dissipative cell, not only have, and have strong energy dissipation capacity from reset function.The appearance of mixed memory alloy damper make from reset, this two big function of highly energy-consuming obtains unifiedly, simply form of structure is convenient to the application of engineering simultaneously.The utility model of mixed memory alloy damper and use and will strengthen civil engineering shock insulation and the survival ability of energy-dissipating and shock-absorbing structure under geological process has important and practical meanings to country and the society stable and the people's lives and property safety when the calamity.
