Embodiment
Describe embodiments of the present invention in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, Figure 2 and Figure 3, the present invention is a kind of active friction energy consumer of ultra-magnetic telescopic half, its shell by
Top cover 6, base plate 7, right baffle-plate 10, right shell body 11, front side board 23 and back side panel 22 are constituted；The inner surface of top cover 6 and base plate 7 is pasted
Having set undersetting on setting upper bracket 9, the friction resistance material of base plate 7 on wear-resisting carbon fiber friction resistance material, the friction resistance material of top cover 6
8.Place multiple sleeves 5 side by side in the middle of two groove profile bearings, sleeve 5 is fixedly connected with undersetting 8 using glue, at the same with it is upper
Leave space between bearing 9 and be not connected to, and contact surface is smooth；Super-magnetostrictive drive 26, ultra-magnetic telescopic are placed in sleeve 5
The two ends of driver 26 are that the hemisphere fixed with bearing supports operating bar 20 and 21, and the power line of super-magnetostrictive drive 26 is by covering
The sulculus export that 5 outer walls of cylinder are opened；Left lever 2 is connected by hex nut 1 with right baffle-plate 10, right pull bar 3 through right shell body 11 with
The sleeve 5 of the rightmost side is connected, and spring 4 is cased between the sleeve 5 of right shell body 11 and the rightmost side on right pull bar 3.
Super-magnetostrictive drive 26 includes sleeve pipe 19, and the top of sleeve pipe 19 is provided through the hemisphere branch of adjusting nut 14
Operating bar 20 in support.Middle part is provided with giant magnetostrictive material 16, and bottom is provided through the hemisphere support of lower adjusting nut 27
Lower operating bar 21.The periphery of giant magnetostrictive material 16 is the aluminum sleeve pipe 17 for being wound with bias coil and excitation coil 18.Up-regulation
The lower section of section nut 14 is provided with the dish sulphur 13 for precompressed, and hemisphere support is upper to be set between operating bar 20 and giant magnetostrictive material 16
It is equipped with arc dumpling 15.
The groove that limits the piston mechanism transverse shifting and can only be moved along bar direction is provided with top cover 6 and base plate 7
Type track.
Wherein, upper bracket 9, undersetting 8, hemisphere support 11 and sleeve 5 constitute piston mechanism, the height of the piston mechanism
Slightly above shell clear height.
The energy consumer both can also be used as intelligent mutative damp friction energy dissipation device as passive friction energy dissipation device.The consumption
Energy device is detachably recombinated, and the size of maximum damping force that can be according to needed for structure takes a driver driving or multiple drives
Dynamic device driving.Its principle is that the piston mechanism that pull bar is acted on by structure in drive shell is transported along shell progress damping power consumption
Dynamic, right pull bar 3 is connected with right hand sleeves 5, and right hand sleeves 5 drive whole piston to move together.Ultra-magnetic telescopic in sleeve 5 drives
Dynamic device 26 is due to the protection by sleeve 5, and failure by shear will not occur for uniform force, while 26 liang of super-magnetostrictive drive
End is hemisphere support operating bar 20 and 21 respectively, and they and the combination formation of arc hinge 15 are articulated and connected so that driver is not by curved
Square, has played the pressure-resistant characteristic intolerant to drawing of super-magnetostrictive drive 26 well.
When it is as passive friction energy dissipation device, because the height of piston mechanism is slightly above the clear height of shell, it is possible to
By adjusting the fastening bolt 25 on top cover 6 come so that precompression is produced between piston and shell, so that the maximum needed for reaching is rubbed
The requirement of resistance.
When it is as intelligent mutative damp friction energy dissipation device because sleeve 5 and the contact surface of undersetting 8 are smooth, sleeve 5 with it is upper
The contact surface of bearing 9 is smooth, while they leave gap in-between, then sleeve 5 will not confined piston mechanism deformation up and down,
The deformation of piston can only be provided by the super-magnetostrictive drive 26 of sleeve inner.Produced when excitation coil passes to current signal
Magnetic field, giant magnetostrictive material produces elongation, and device limits its elongation, just generates pressure, so adds rubbing surface
Normal pressure, so as to serve the controllable of frictional force, you can cause that driver is exerted oneself with the electric current by control external power supply.That
The relation that electric current is exerted oneself with actuator is F=μ N=μ KI, and I is controllable input current, and K is single actuator electricity-power transformation system
Number, μ is coefficient of friction.
To sum up, the characteristics of exerting oneself big present invention utilizes giant magnetostrictive material, for piezoelectricity friction energy consumer,
Service behaviour is more stable, bigger and convenient disassembly of exerting oneself.Which solve existing piezoelectricity friction energy consumer exert oneself it is small be unsuitable for knot
The technical problem applied in structure earthquake resistant control and the application for having promoted giant magnetostrictive material, dependable performance etc. big with exerting oneself
Advantage.
