Description
Technical field
This utility model relates to high-temperature superconducting magnetic levitation technology, particularly to a kind of permanent magnetic guideway.
Background technology
With the electromagnetic suspension (EMS) based on electromagnetic attraction and electromagnetic repulsion force and electrodynamics suspension (EDS) skill
Art is compared, and high-temperature superconducting magnetic levitation technology relies on the flux pinning between high-temperature superconductor bulk and external magnetic field
Effect realizes passive self-stabilization and suspends.This technology is without active control, and simple in construction, therefore has become as
One of ideal chose of practical magnetic levitation technology.It is limited to the particular/special requirement of high temperature superconducting magnetic suspension system, forever
The external magnetic field motivation needs that magnet is provided meet have in track cross-section high magnetic flux density and magnetic field ladder
Degree, then needs along direction of traffic to meet without magnetic field gradient and the particular/special requirement that possesses the highfield uniformity,
Thus monolithic permanent magnet can not be only relied on this magnetic field excitation is provided, and need to introduce special permanent magnet combination structure,
The splicing of polylith permanent magnet is assembled, constitutes a complete permanent magnet mechanism, be applied to super-conductive magnetic suspension row
Che Shi, normally referred to as permanent magnetic guideway.
Existing 15 days since the manned high-temperature superconducting magnetic levitation laboratory vehicle in first of the world in 2000 comes out, though
Right every basic research is carried out the most comprehensively and achievement is distinguished, but permanent magnetic guideway of the prior art there is also
Problem and defect.
At present, the structure of permanent magnetic guideway of the prior art mainly has three kinds:
The first structure: new century edition single peak type guide rail (as shown in Figure 1) of traffic direction field homogeneity.
The second structure: the poly-magnetic provided in Chinese patent CN03234867.3 is effective and cost is low
Halbach type permanent magnetic guideway (as shown in Figure 2).
The third structure: compound permanent magnetic guideway provided in Chinese patent CN201310073869.4 (as
Shown in Fig. 3).
Fig. 1 is the cross sectional representation of new century edition permanent magnetic guideway of the prior art.As it is shown in figure 1, new century edition
Permanent magnetic guideway is made up of permanent magnet material 12 and carbon steel 11, and the magnetic field of permanent magnet is assembled in carbon steel,
Produce the strongest magnetic field in the upper and lower both sides of permanent magnetic guideway, at guideway centreline, surface induction intensity reaches 1.2T.
Fig. 2 is the magnetic line of force scattergram of new century edition permanent magnetic guideway of the prior art.As in figure 2 it is shown, this structure
The Distribution of Magnetic Field of the upper and lower both sides of guide rail full symmetric, but only used the magnetic above guide rail during actual application
, this not only wastes resource, increases cost, and below guide rail, complete unemployed high-intensity magnetic field is also led
The installation of rail and transport bring great inconvenience, for ensureing safety, need to increase in bottom one layer thicker
Non-magnet_conductible material.
Fig. 3 is the schematic cross-section of the second permanent magnetic guideway of the prior art.As it is shown on figure 3, the second is forever
Magnetic conductance rail is made up of some pieces of horizontal magnetised magnets 31 and vertical magnetised magnets 32, the magnetization of this set of permanent magnets
Direction arranges according to the mode of Haier's Bach's array (Halbach Array), such that it is able to use less amount of magnetic
Body produces stronger magnetic field.
Fig. 4 is the magnetic line of force scattergram of the second permanent magnetic guideway of the prior art.As shown in Figure 4, from magnetic force
From the point of view of line distribution angle, utilize Halbach structure the major part magnetic line of force can be transferred to the work above guide rail
Region, is greatly improved the utilization rate of magnetic energy in permanent magnet material, reduces guide rail lower surface and downside is empty
Interior magnetic flux density, reduces the installation difficulty of whole section of guide rail and the difficulty of transport.But, from the magnetic line of force
In scattergram it can be seen that due in Halbach array the direction of magnetization of adjacent magnets different, by adjacent magnetic
The magnetic pressure effect of body, between adjacent magnets, repulsion is relatively big, and installation difficulty is high, needs specially designed matched clamp
Could realize installing accurately with the mechanical arm of high intensity.
And, when, above high-temperature superconducting block is suspended in permanent magnetic guideway and when quickly running along direction of traffic, driving a vehicle
Direction magnetic field gradient can cause the flux motion within high-temperature superconducting block and cause loss, reduces superconduction magnetcisuspension
The performance of floating system.The speed of service is the fastest, and the decay of suspendability is the most notable, is likely to result in height time serious
Local within temp. superconductive bulk quenches, and directly threatens the security performance of system.
But, for permanent magnetic guideway, major part is permanent magnet material.A kind of functional material with high-intensity magnetic field,
Its ductility and structural strength are the most poor.Therefore, regardless of the mode of the direction of magnetization in guide rail cross section,
In actually used, the permanent magnet owing to producing is bulk material, and by material structural strength, magnetize sky
Between etc. factor impact, self physical dimension has certain length to limit, and is therefore by sectional guide rail along direction of traffic
Section assembly.Along direction of traffic, the length permanent magnet material length of carbon steel is many, plays carbon steel material pcrmeability relatively
High characteristic, can relax the magnetic field that carbon steel both sides permanent magnet causes because of alignment error or the unequal reason that magnetizes
Distortion.
Fig. 5 is the schematic cross-section of the third permanent magnetic guideway of the prior art.As it is shown in figure 5, compound forever
Magnetic conductance rail is made up of the opposed combination of permanent magnetism two pieces of horizontal magnetised magnets 51 and poly-magnetic carbon steel 52, forms main magnetic circuit,
Assemble magnetic energy and to space divergence, the carbon steel that wherein pcrmeability is higher, can effectively suppress the magnetic field of direction of traffic
Irregularity；Increasing by two pieces of direction of magnetizations on permanent magnetism opposed combination both sides is that magnet 53 straight down forms auxiliary magnetic
Road, is used for assisting poly-magnetic and magnetic circuit to guide, utilizes the magnetizability that magnet self possesses by the magnetic energy of permanent magnetic guideway
It is directed in the working region above guide rail.
Fig. 6 is the magnetic line of force scattergram of the third permanent magnetic guideway of the prior art.As shown in Figure 6, from magnetic flux
Apparently, this structure still can not constitute complete Halbach type closed magnetic loop to Density Distribution angle.Track extends
Property angle (the guide rail structure sectional view after extension is as shown in phantom in Figure 5), track structure extension after be equivalent to
Being that permanent magnet straight up replaces to poly-magnetic carbon steel by the direction of magnetization in Halbach structure, magnetism-collected structure is the completeest
Whole, poly-magnetic effect is not as good as the Halbach array of structural integrity.
