Specific embodiment
Below in conjunction with accompanying drawing and technical scheme, elaborate specific embodiment of the present utility model.
Multidirectional Self-resetting marmem lead damper mainly includes：Connecting rod 1, the first inner core-left cover 2, SMA bullet
Spring fixture 3, outer tube-fixing bolt 4, SMA spring 5；3rd inner core 6, outer tube 7, fixed plate 8, prestressing force adjust ring flat-plate 9, SMA silk
10th, pull bar 11, right side draw ring 12, left side draw ring 13, connecting cylinder 14, outer tube-left cover 15, inner core-fixing bolt 16, prestressing force
In adjustable plate 17, Zola's plate 18, the first lead 19, the second lead 20, the first inner core 21, the second inner core 22, right pulling plate 23, first
Cylinder-right shell body 24, SMA silk fixture 25, outer tube-right cover plate 26；Left side draw ring 13, right side draw ring 12 are on axis to be mutually 90
Degree angle arrangement, purpose, in addition to making antivibrator and structure and being connected firmly, simultaneously takes account of both sides and is stretched and reverses two sides
To moment, make damping more preferable.
This antivibrator is applied to multidirectional stressed situation, illustrates its passive energy dissipation respectively when ring reverses and during radial direction tension and compression
Mechanism.First, move to left when pull bar 11 stretches drive the first inner core 21 to the left, the first inner core-left cover 2 promotes Zola's plate 18 to the left
Mobile, thus driving the second inner core 22 being welded on the right side of it to move to left.Second inner core 22 is toward moving left and the 3rd inner core 6 occurs phase
To displacement, because the 3rd inner core 6 is fixed on outer tube 7, shearing is located at the second lead between the second inner core 22 and the 3rd inner core 6
20；SMA spring 5 left end stretches to the left with Zola's plate 18 simultaneously.When pull bar 11 stretches to the right drive the first inner core 21 and moves to right, by
Limited by Zola's plate 18 in the second inner core 22, make the first inner core 21 and the second inner core 22 that relative displacement to occur, shearing is located at the
The first lead 19 between one inner core 21 and the second inner core 22；Meanwhile, the first inner core-right shell body 24 will promote right pulling plate 23
Move right, always stretch to the right SMA spring 5.Make it with outer tube 7, relative displacement occur because pull bar 11 moves to left, stretch SMA silk
10.SMA silk 10, SMA spring 5 stretching power consumption in whole process, the second lead 20, the first lead 19 produce after being subject to shear yielding
Plastic deformation energy dissipation.After work, due to SMA silk, SMA spring stronger super-elasticity so that whole device is being moved through
Return to original position afterwards.
When right side pull bar 11 is relatively rotated with left-side connecting bar 1, because Zola's plate 18, right pulling plate 23 are connected to place
In the two ends of the SMA spring 5 of pretensioned state, and Zola's plate 18 is welded in the left end of the second inner core 22, limits the second inner core
22 is freely rotatable.First, pull bar 11 rotates and drives the first inner core 21 being welded in its left end that relative rotation occurs, thus circumferentially
Shearing is embedded in the first lead 19 between the first inner core 21 and the second inner core 22；With the increase bearing high twisting resistance, positioned at Zola
SMA spring 5 between plate 18 and right pulling plate 23 is stretched torsion, and the second inner core 22 rotates and the being fixed on outer tube 7
There is relative rotation in three inner core 6, thus circumferentially shearing is embedded in the second lead 20 between the second inner core 22 and the 3rd inner core 6.?
In the whole process reversed, Zola's plate 18 drives left end SMA spring 5 circumferentially to rotate around fixed plate 8 upper annular bore, sends out with right-hand member
Raw relative rotation, during this spring by be stretched and twisting resistance effect.And after reversing, because SMA spring inherently has
Super-elasticity, Zola's plate 18 and the second inner core 22 self- recoverage will be driven to initial position.During whole torsion, pull bar 11
Torsion makes itself and outer tube 7 circumferentially relative rotation occur, thus stretching is fixed on sequentially passes through outer tube on prestressing force regulation ring flat-plate 9
7th, the prestressing force SMA silk 10 of pull bar 11.After torsion, because SMA wire material has super-elasticity, make pull bar 11 self- recoverage to initial bit
Put.In whole process, power consumption is reversed in SMA silk 10, SMA spring 5 stretching, and the second lead 20, the first lead 19 are circumferentially sheared
Plastic deformation energy dissipation is produced after surrender.Prestressing force SMA silk and SMA spring not only have good highly energy-consuming characteristic, and bear respectively
The Self-resetting of two sets of inner barrel devices of duty, so that it is guaranteed that whole device after a procedure can parking position accuracy.
This utility model is mainly characterized in that, makes due to carrying out energy-dissipating and shock-absorbing highly energy-consuming using shearing-type metal lead and SMA material
It has stability by force, good endurance, damping force scalable.Device makes adjustable damping force lifting using double-deck lead.
