Description
Technical field
The utility model belongs to technical field of civil engineering, relates to a kind of mixed type shape memory alloy multi-dimensional vibration isolator.
Background technology
How to alleviate the response of engineering structures under extraneous loads such as high wind and earthquake effectively, the performance of combating a natural disaster that improves structure is one of problem demanding prompt solution in the field of civil engineering.Structural vibration control can alleviate the damage under the effect of structure outer load effectively, improves the performance of taking precautions against natural calamities of structure.Vibration isolation can consume vibrational energy by vibration damping, isolation mounting, perhaps offsets the influence of external load effect to structure by applying energy.Specifically be to install certain device, mechanism or minor structure at some position of structure, to change or adjustment dynamic Characteristics of Structure or dynamic action, dynamic response under the effect of structure outer load is reasonably controlled, guaranteed the people in structure itself or the structure, the safety of instrument and equipment.
Vibration isolation technique is relatively ripe, yet as a kind of passive control device, durability and corrosion resistance are ubiquitous problems in the present vibration isolator.Be easy to wear out as the rubber dottle pin, viscous damper is difficult safeguards that frcition damper can not reset certainly, and mild steel damper has plasticity permanent set etc.Marmem is a kind of new function material, has shape memory effect, super-elasticity and high damping characteristic.The marmem vibration isolator is compared with the vibration isolator of other types, advantages such as have durability and corrosion resistance and good, 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, and energy dissipation capacity is limited.
In addition, the response under random load effects such as earthquake, high wind and mechanical oscillation of engineering structures or member is at random, and one of performance is exactly the randomness of vibratory response direction.Damper or the vibration isolator of developing only has the passive energy dissipation ability of single direction usually at present, the difficult multidimensional Passive Control that realizes in the engineering own.
Therefore, the comprehensive utilization super-elasticity runback potential energy power of austenite shape memory alloy and the high damping characteristic of martensite marmem are developed a kind of vibration isolator with multi-dimensional direction and civil engineering structure is reduced unfavorable vibration are had important practical significance.
Summary of the invention
The utility model provides a kind of mixed type shape memory alloy multi-dimensional vibration isolator, its objective is to solve short, the corrosion-resistant of existing vibration isolator durability, and energy dissipation capacity is limited, can not reset certainly, problem that can only the single direction vibration isolation.
The technical solution of the utility model is as follows:
Mixed type shape memory alloy multi-dimensional vibration isolator mainly is made up of upper flange bolt hole, upper flange, clamping bolt, inner core, martensite shape memory alloy energy-consuming springs, austenite shape memory alloy twisted wire, urceolus, chassis, thin-walled shape memory alloy hollow ball, lower flange bolt hole and lower flange.Main technical schemes is: interior steel cylinder upper end is connected with upper flange, the lower end is connected with the steel chassis, outer steel cylinder lower end is connected with lower flange, interior steel cylinder is coaxial with outer steel cylinder, both are connected with the austenite shape memory alloy twisted wire by three layers of martensite shape memory alloy energy-consuming springs, and the austenite shape memory alloy twisted wire is through in the martensite shape memory alloy energy-consuming springs; Every layer of eight groups of martensite shape memory alloy energy-consuming springs that contains and austenite shape memory alloy twisted wire are along steel cylinder circumference radial level symmetric arrangement, being shape memory alloy energy-consuming springs and marmem twisted wire is penetrated by the hole of outer steel cylinder one side, hole by the corresponding side of interior steel cylinder passes, its two ends are fixed on outer, interior steel cylinder, and the austenite shape memory alloy twisted wire is by the mid point of clamping bolt prestretched strain to its super-elasticity platform; Three layers of thin-walled shape memory alloy hollow ball are placed in the inside of outer steel cylinder; By upper flange and lower flange vibration isolator is fixed on the position that structure need be carried out vibration isolation.
When interior steel cylinder planar moves with respect to outer steel cylinder, interior steel cylinder is drawing the martensite shape memory alloy energy-consuming springs and the austenite shape memory alloy twisted wire partly extends and part alternately changes with shortening, thereby stable damping force is provided and consumes big energy, to suppress the vibration of any direction in structure or the member plane, because martensite shape memory alloy energy-consuming springs and austenite shape memory alloy twisted wire along steel cylinder circumference radial level symmetric arrangement, therefore can guarantee the reset function of vibration isolator in any horizontal direction; When interior steel cylinder with respect to outer steel cylinder generation vertical displacement with reverse; the thin-walled shape memory alloy hollow ball will consume the energy of vertical motion; because the austenite shape memory alloy twisted wire is in extended state all the time in this vibration processes, so this damper has the vibration damping and the reset function of vertical and torsional direction.
Effect of the present utility model and benefit are embodied in the super-elasticity runback potential energy power that fully utilized austenite shape memory alloy and the high damping characteristic of martensite marmem, realized the vibration isolation of multi-dimensional direction, and this vibration isolator has characteristics such as no permanent set, simple structure, easy installation and removal, the Passive Control that can be widely used in field of civil engineering, effectively reduce structure or member vibration and shake by force after permanent set.
