Embodiment
In order to solve non-adjustable, the yielding and aging problem of rigidity of existing vibration damper, the purpose of this patent is the structure that proposes the adjustable super-conductive magnetic suspension vibration damper of a kind of rigidity that extensively is suitable for.This kind structure is according to the principle of super-conductive magnetic suspension, and the magnet of conduct of use electromagnet and superconductor coupling, can reach the adjustable purpose of rigidity.
The super-conductive magnetic suspension technology is based on the intrinsic the Meissner effect of superconductor, and superconductor can produce stable suspending power/suspension force with magnet after entering superconducting state.The magnetic intensity of adjusting magnet just can be regulated the suspending power/suspension force between superconductor and the magnet accordingly.Making superconductor enter superconducting state needs low temperature environment, and this low temperature environment is generally kept by liquid helium or liquid nitrogen.Can produce stable suspending power or suspension force between superconductor and the magnet, this depends on the position relation of superconductor and magnet.Superconductor is positioned at magnet when top, and fixing magnet has suspending power to superconductor freely; Otherwise superconductor is positioned at magnet when below, and fixing magnet has suspension force to superconductor freely.Adopt a cold mode of magnetization that superconductor is provided with suitable hoverheight or suspension height.In case superconductor departs from this position under external force, the power of this equilibrium position will be subjected to pointing to.
Specifically referring to Fig. 1, the outward appearance that has shown this super-conductive magnetic suspension vibration damper is a cylindrical structural.End cap 2 can be connected with bolt with vibration damper shell 1.Connecting rod 10 is a movable part, can do axial straight reciprocating motion.
Fig. 2 has shown the internal structure of this super-conductive magnetic suspension vibration damper.Be fixed with lower electromagnet 4 in the bottom surface of vibration damper shell 1.Several lower electromagnets 4 can be arranged in different arrays according to actual usage requirement, and are as annular, square etc.The inboard of end cap 2 is fixed with electromagnet 3.Same, electromagnet 3 can be arranged in different arrays according to actual usage requirement on several, and is as annular, square etc.Arbitrary electromagnet is formed by iron core 5 and coil 6 two-part.By the size of current in the regulating winding 6, magnetic intensity that can regulating magnet.Dewar 8 is a hollow structure, and is connected with connecting rod 10.Connecting rod 10 also is a hollow structure, can be by connecting rod 10 annotate in Dewar 8 liquid helium or liquid nitrogen.Superconductor bulk 9 is connected in the both sides up and down of Dewar 8.This superconductor bulk 9 contacts well with Dewar 8, thereby the liquid helium in the Dewar 8 or liquid nitrogen can contact cooling to superconductor bulk 9.Madial wall at vibration damper shell 1 also is fixed with chute 7, and its quantity can be decided according to usage requirement.The respective outer side edges of this chute 7 and Dewar 8 makes that Dewar 8 can only the natural pond axial motion, and can not rotate.In the using process, at first the magnetic intensity of regulating magnet 3,4 is fixed on Dewar 8 a suitable position then to suitable size, afterwards filling liquid helium or liquid nitrogen in Dewar 8, make superconductor bulk 9 enter superconducting state, remove the position constraint of Dewar 8 at last.Drive Dewar 8 in case connecting rod 10 bears vibrations and move vertically, superconductor bulk 9 will depart from the equilibrium position and be subjected to the power of the sensing Dewar equilibrium position of power-on and power-off magnet 3,4.If the rigidity of wanting to regulate this vibration damper only needs the magnetic intensity of corresponding regulating magnet to get final product.
Fig. 4 has shown the structure of the Dewar 8 in this super-conductive magnetic suspension vibration damper, and can see has the structure that cooperates with chute 7 in the side of Dewar 8.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
