The setting of 7 face of hole, two leads 6 are sequentially embedded respectively in three location holes 7 of corresponding position.It is further by setting lead 6
Increase the energy consumption of damper.When main structure vibration, the relative displacement between two push-pull rods shears lead 6 back and forth, produces
Raw energy consumption effect.After vibration, due to SMA good automatic recovery abilities, so that damper restores reset condition, to reach
To self-healing function.
Fixed on each outer wall of first push-pull rod 1 there are two cover boards 8, and two cover boards 8 cover be located at two respectively
The end of a lead 6.Lead 6 is locked in location hole 7 by setting cover board 8, guarantees that lead 6 can be just when damper work
Often shearing.Cover board 8 is fixed on the first push-pull rod by four bolts.
Connected between two side arm 1-1 of the first push-pull rod 1 by several high-strength bolts 9 arranged along its length
It connects, the second push-pull rod 2 offers long hole 2-2 along its length, and passes through institute between the second push-pull rod 2 and the first push-pull rod 1
It states long hole 2-2 and several high-strength bolts 9 is slidably connected.Guarantee the phase between two push-pull rods by setting long hole 2-2
Mutually displacement.
The quantity of the high-strength bolt 9 is three.
First push-pull rod 1 includes that connector 1-2, two baffle 1-3 arranged in parallel and four are vertically arranged
Locating rod 1-4, wherein the opposite both ends for being installed in two baffle 1-3, and connector 1-2 and two two-by-two four locating rod 1-4
One end of a baffle 1-3 passes through two locating rod 1-4 respectively and fixes as one, and U-shaped through slot 1-21 is offered on connector 1-2,
And the open end of the U-shaped through slot 1-21 is towards two baffle 1-3 setting, two tops locating rod 1-4 being often oppositely arranged it

Working principle:
Pulling action: it is for the direction shown in attached drawing, the first push-pull rod 1 is fixed, damper is loaded
The second push-pull rod 2 is set to stretch out and (stretch to the right), the card slot 2-1 inner wall of 2 upper left side of the second push-pull rod drives the two of left side
A reset bar block 3 flips outward, and the lower end of reset bar block 3 moves right at this time, and upper end is moved to the left, marmem
Silk 5 is stretched；The pulling force of shape-memory alloy wire 5 makes the trend of the oriented interior overturning of two reset bar blocks 3 on right side, passes through the right side
Two blocks 4 of side prevent two reset bar blocks 3 on right side from rotating inward.
Shape-memory alloy wire 5 is since its recoverable ability is by the reset bar block 3 of 2 left end of the second push-pull rod after unloading
It is withdrawn into original state.
Compressed action is i.e. fixed by the first push-pull rod 1, is moved to the left the second push-pull rod 2 damper load, work
Principle is similar with the working principle of pulling action.
When damper works, can a push-pull rod fix, another push-pull rod is mobile, can also two push-pull rods are opposite moves
It is dynamic.
