Abstract

A superelastic pull, compression and torsion damper with marmem for engineering structure is composed of external steel pipe, the internal steel pipe whose one end is coaxially in the external one, the marmen wire which passes symmetrically through the holes on the walls of both steel pipes, and two fixtures for fixing both ends of marmen wire to the external surface of external steel pipe. It can suppress the relative straight line and rotation vibration displacement between two structural members.

Description

The engineering structures super elastic shape memory alloy draws, presses, turns round damper
One, technical field
The present invention is a kind of device that is applied to play in the engineering structures effect of damping antivibration, especially a kind of damper that possesses anti-tensile, compressive, torsional effect simultaneously.
Two, background technology
The vibration of using damper to suppress engineering structures is a kind of effective means.The engineering structures damper that uses can effectively bear Tensile or Compressive Loading at present, can suppress the relative straight-line oscillation displacement between structural element.And between structural element except relatively direct vibration displacement, general always being accompanied by relatively rotates vibration displacement.Existing engineering structures owing to self structure, can not directly suppress the vibration displacement that relatively rotates between structural element with damper.
Three, technology contents
1, technical problem
The purpose of this invention is to provide a kind of engineering structures super elastic shape memory alloy and draw, press, turn round damper, this damper both can suppress straight-line oscillation displacement relatively between structural element, vibration displacement can be suppressed to relatively rotate between structural element again, thereby the ground decay that structural vibration response, accelerating structure shake can be more effectively suppressed.
2, technical scheme
Engineering structures super elastic shape memory alloy of the present invention draws, press, turn round damper, this damper is by shape-memory alloy wire, anchor clamps, outer steel pipe, interior steel tube place forms, one end of interior steel pipe is arranged in outer steel pipe and is positioned on same the axis with outer steel pipe, shape-memory alloy wire radially is fixed on the symmetrical side of outer steel pipe on the steel pipe outside, being shape-memory alloy wire is penetrated by the hole of outer steel pipe one side, side by interior steel pipe, pass through axial line again, another symmetrical side by interior steel pipe passes then, at last the hole by another symmetrical side of outer steel pipe passes, the two ends of memory alloy wire are fixed on the outer steel pipe by anchor clamps respectively, the footpath of steel pipe and outer steel pipe made progress in shape-memory alloy wire was distributed in by many, and adjacent two shape-memory alloy wires are on axially being, the following setting.Another kind of structure is that the two ends of steel pipe are provided with interior steel pipe and corresponding shape-memory alloy wire structure respectively outside, and forming middle is that outer steel pipe two is the damper structure of interior steel pipe.Also having a kind of structure is the structure that two of interior steel pipe is provided with two outer steel pipes and corresponding shape-memory alloy wire respectively, is the damper structure of outer steel pipe for interior steel pipe two in the middle of forming.Shape-memory alloy wire can be the silk cable of several shape-memory alloy wires compositions.
During use, the outer and inner tube of damper is fixed between the difference of structure different component or same member, and when between two fixed ends relative displacement being arranged, outer and inner tube also just has relative displacement, and no matter this relative displacement is a straight line
Relative displacement still relatively rotates displacement, and shape-memory alloy wire reaches the purpose of the horizontal vibration, vertical motion and the twisting vibration that suppress structure simultaneously all with the stretcher strain power consumption.
3, technique effect
" the engineering structures super elastic shape memory alloy draws, presses, turns round damper " of (1) being invented, because shape-memory alloy wire has higher rigidity, use damper also just to have enough rigidity, effectively distortion and the stability of control structure under wind load and geological process can reduce the creep deformation of structure under the sustained load effect effectively.
" the engineering structures super elastic shape memory alloy draws, presses, turns round damper " of (2) being invented, can absorb vibrational energy effectively by the super elastic characteristics of the shape memory alloy material in the damper device, thereby reduce the vibratory response of structure under wind load and geological process effectively, improve the vibration attenuation speed of structure under wind load and geological process effectively.
" the engineering structures super elastic shape memory alloy draws, presses, turns round damper " of (3) being invented can be suppressed horizontal vibration, vertical motion and the twisting vibration of structure simultaneously, can be used for the vibration damping of various engineering structures such as building structure, bridge construction and large-span structure.
" the engineering structures super elastic shape memory alloy draws, presses, turns round damper " of (4) being invented, the shape memory alloy material by working strength height, corrosion-resistant, antifatigue be as the power consumption material, thereby have the long and low characteristics of maintenance requirement of life-span.
" the engineering structures super elastic shape memory alloy draws, presses, the turns round damper " simple structure, easy for installation of (5) being invented.
Four, description of drawings
Fig. 1 is a general structure schematic diagram of the present invention.Shape-memory alloy wire 1, anchor clamps 2, outer steel pipe 3, interior steel pipe 4 are wherein arranged.
Fig. 2 is that the A-A of Fig. 1 of the present invention is to the sectional structure schematic diagram.Wherein porose 5.
Fig. 3 is the structural representation of two interior steel pipes, an outer steel pipe.
Fig. 4 is the structural representation of two outer steel pipes, an interior steel pipe.
Five, specific embodiments
