Technical field
The present invention relates to the high-temperature superconducting magnetic levitation technical field, specifically is a kind of automobile-used double-deck high-temperature superconductor magnetic suspension system.
Background technology
The high-temperature superconducting magnetic levitation technology owing to the unique flux pinning characteristic of high-temperature superconductor, has the suspension advantage of passive self-stabilization, shows good prospects for application in fields such as frictionless bearing, flywheel energy storage, track traffics.Wherein, The huge attractive force of high-temperature superconducting magnetic levitation technology at novel (at a high speed, environmental protection, characteristics such as comfortable) track vehicle in future showed in the birth of first the manned high-temperature superconducting magnetic levitation laboratory vehicle in China world in 2000, caused the extensive concern of international community.At present, states such as Germany, Russia, Brazil, Japan all develop high temperature superconductor magnetic levitation vehicle laboratory model machine, and each state is all in the practicalization of making great efforts to advance high temperature superconductor magnetic levitation vehicle.How further to improve the load-carrying capacity and the stability of existing high temperature superconductor magnetic levitation vehicle system, become one of them technological emphasis.
In existing various countries high temperature superconductor magnetic levitation vehicle system, all be to adopt individual layer high-temperature superconductor bulk and tracks of permanent magnetism mutual action to realize suspending.Consider the preparation technology of superconduction block material, generally between 12-15 mm, in this scope, the lift force of bulk is approximate to reach capacity the bulk thickness of commercial application.In traditional individual layer high-temperature superconductor magnetic suspension system, be difficult to reach the target that suspension property is optimized through the thickness that increases every superconduction block material again.
Summary of the invention
The purpose of this invention is to provide a kind of automobile-used double-deck high-temperature superconductor magnetic suspension system, the double-deck high-temperature superconductor physical efficiency in this invention improves the suspending power and the guidance capability of suspension system simultaneously.Adopt this kind magnetic suspension system stable suspersion ability strong, help applying of high temperature superconductor magnetic levitation vehicle.
The present invention realizes like this; Construct a kind of automobile-used double-deck high-temperature superconductor magnetic suspension system; It is characterized in that: comprise by permanent magnet and gather track that magnetic material etc. constitutes, be fixed in the low-temperature (low temperature) vessel in the car body shelf; The low-temperature (low temperature) vessel internal fixation has the high-temperature superconducting block layer, and the high-temperature superconducting block layer is the double layer design that bulk 103a of lower floor and upper strata bulk 103b stack.
According to a kind of automobile-used double-deck high-temperature superconductor magnetic suspension system of the present invention, it is characterized in that: said double layer design is that bulk 103a of lower floor and upper strata bulk 103b directly stack.
According to a kind of automobile-used double-deck high-temperature superconductor magnetic suspension system of the present invention, it is characterized in that: said double layer design is that bulk 103a of lower floor and upper strata bulk 103b dislocation stack.
According to a kind of automobile-used double-ply high-temperature superconductor suspension system of the present invention, it is characterized in that: the corresponding thickness of each layer of high-temperature superconducting block layer bulk is 12-15 mm.
The present invention increases the upper strata superconductor can play the purpose that improves original individual layer suspension system lift force and guidance force performance simultaneously, can be used for optimizing existing individual layer high temperature superconducting magnetic suspension system, improves the load-carrying ability and the stability of levitated superconducting magnet train.
In high temperature superconducting magnetic suspension system, lift force is superconduction block material induced inside electric current and the interactional macro manifestations of foreign field, belongs to Lorentz force.Therefore, the foreign field condition is the necessary condition that lift force produces.In existing individual layer high-temperature superconductor magnetic suspension system, on the one hand, the distinctive flux pinning ability of superconduction block material makes a part of applying a magnetic field magnetic flux can penetrate high-temperature superconductor; On the other hand, bulk in-to-in superconduction zone shows a kind of shielding action to using magnetic field.The superposition decision that the magnetic field of final bulk top is penetrated and shielded by magnetic flux, this makes still has certain applying a magnetic field to utilize above existing individual layer high-temperature superconducting block.Therefore one deck superconductor that increases newly in existing individual layer high-temperature superconductor surface can obtain certain lift force, reaches the purpose of the load-carrying ability that improves suspension system; So compare with original individual layer high-temperature superconductor magnetic suspension system, the lift force of automobile-used double-deck high-temperature superconductor magnetic suspension system according to the invention and guidance force all can obtain to improve, and the stable suspersion ability is stronger.
The invention has the advantages that: increase the upper strata superconductor and can play the purpose that improves original individual layer suspension system lift force and guidance force performance simultaneously.Experiment showed, under the service conditions of cold height 30mm in representative type field and operating altitude 15mm, can bring 16.9% lift force to improve and 8.8% guidance force raising; Under cold service conditions of null field and lower operating altitude condition, the gain effect of double-deck superconductor will be more remarkable simultaneously.
In practical application,, just calculate superconductor separately and become to see originally that the cost performance of the new layer superconductor of increase is lower because the superconduction block material price is relatively costly.Yet, become to see originally apart from the high temperature superconductor magnetic levitation vehicle entire system for the length of final application, under same suspending power requires, adopt double-deck superconductor scheme than comparing the many of economy by the scheme that increases the tracks of permanent magnetism cross section, have using value.
