Description
Affiliated technical field
The invention belongs to the magnetic suspension train technology, the rail that be specifically related to the magnetic suspension train car body, cooperates car body to use, and the high speed train that comprises the two.
Background technology
Magnetic suspension train before this, " driving " and " floating outstanding " two kinds of functions are that compatible going up at one " sensing interface " realized mostly.For example; Big gap " repulsion type " magnetic suspension train of Japan must start under the wheel track contact condition and quicken; Have only when the speed of a motor vehicle to exceed a certain boundary, during a certain numerical value of the also corresponding serious offense of repulsion, train is just liftoff to be floated.And for example De Guo " little gap ", long stator " attractive " magnetic suspension train, its floating outstanding gap only is 8 to 10 millimeters, adopt the synchronous linear electric motor principle to realize driving and floating hanging: the DC electromagnet on " car body ", and " magnetic pull " between " rail " long stator, its " front and back " component are used for realizing driving, " up and down " component be used for realizing floating outstanding, " about " component is used for realizing guiding.And the suspension of this suction type requires the strict maintenance of width in " little gap " between car, the rail constant.If the gap is less than setting value, vehicle body then can be inhaled dead; Otherwise greater than setting value, vehicle body then can weigh down and take off as if the gap.Be to guarantee the strict conservation in gap, an inverse feedback robot control system(RCS) cover " absolute reliable ", high-precision, that be made up of photosensitive sensing element and " department's clothes of answering in wink are in real time put " is essential.The control device of this high precision, hightech difficulty has increased floating outstanding cost greatly.
Summary of the invention
The purpose of this invention is to provide the magnetic suspension train car body that a kind of technology is simple, cost is low but safe in utilization, the rail that cooperates car body to use, and the high speed train that comprises the two.
The technical scheme of magnetic suspension train car body of the present invention is: train body is made of one or more single car body, wherein,
1, the transversal surface of each single car body bottom all is isosceles trapezoid shape wide at the top and narrow at the bottom;
2, all be fastened with a kickboard on two inclined-planes of each single car body bottom, have permanent magnet on said the kickboard;
3, also be fastened with drive plate on two inclined-planes of at least one single car body bottom, kickboard and drive plate stagger not overlapping at the restraint location of car body bottom mutually, the grizzly bar that has metal sheet palisade armature, grid shape armature on the said drive plate is transversely arranged along car body, and in the both side ends short circuit.
The technical scheme of magnetic suspension train rail of the present invention is: the transversal surface of rail foundation ditch all is isosceles trapezoid shape wide at the top and narrow at the bottom, on two inclined-planes of rail foundation ditch, be equipped with can produce magnetic field and with a car body bottom kickboard opposite face be the rail of same pole.Like this, the magnetic repulsion between the kickboard of rail and car body bottom just can float train.Rail can be permanent magnet, also can be the excitatory rail of dynamic tracking, sectional power supply.
Magnetic suspension train car body of the present invention and rail are to be mutually related, must to use simultaneously.
High speed train of the present invention comprises above-mentioned magnetic suspension train car body and rail.
Below the further floating principle of analysis of magnetic:
If under the identical condition in gap, from the viewpoint of repulsion equivalence, with at the bottom of being installed in car, car body is produced a plurality of kickboards of total repulsion, amounting to becomes the direct current of equivalence magnetic potential F
1Simultaneously, with " magnetic unit " sum total that faces with it on the rail in the areal extent, also be converted into an Equivalent DC magnetic potential F
2, then can derive a foolproof uplift pressure formula:
Uplift pressure=(coefficient of colligation) * (F
1* F
2)/(calculated gap)=the car body gross weight
Wherein, the difference between coefficient of colligation reflection measured value and the theoretical value.Calculated gap also is not equal to mechanical clearance between car, road, and it depends on concrete physical structure and corresponding math modeling.
With above-listed formula transposition, can obtain the expression formula of calculated gap:
Calculated gap=(coefficient of colligation) * (F
1* F
2)/car body gross weight
If the F of rail side
2Be constant, we can compoundly on the permanent magnet of a kickboard allow it become built-up magnet with DC electromagnet, and then the negative feedback of is regulated " on the kickboard DC current size, allow F
1Be directly proportional with the car body gross weight, just can keep the gap conservation.
Adopt the direct current mode, owing to there is not eddy current to exist, the ohmic loss in the magnet coil is littler than exchange way, and the repulsion that is produced is constant rather than pulsation.If adopt pure permanent magnetism mode, the floating cost of the magnetic when then moving can be zero.
In fact, the fastening drive plate in car body bottom has constituted the unidirectional DC machine of straight line that the driving train advances jointly with the rail that can produce magnetic field.During the work of the unidirectional DC machine of this straight line, add a vdc in the both side ends of grid shape armature, then grid shape armature will vertically constantly advance along track.The principle of work of the unidirectional DC machine of this straight line below is described:
Fig. 1 is the prototype of faraday's " one-way motors ".Among the figure, the 1st, ungulate permanent magnet, the 2nd, rosette, the 3rd, by "+" electrode connection terminal of drawing on disk 7 edges, the 4th, by "-" electrode connection terminal of drawing in the rotating shaft; The 5th, the jiggle bar when doing the electrical generator use.When jiggle bar 5 is rotated along clockwise direction, between two sliding brushs of all edges of disk and rotating shaft, just set up a DC potential.If connect load between connection terminal 3 and 4, electric current will flow to "-" utmost point along load circuit from "+" utmost point.According to " reciprocity principle " of motor, if the direction of transducing is turned around, between "+", "-" two brushes, add a vdc from the outside, and the jiggle bar in the rotating shaft 5 is taken off, change mechanical load into.At this moment, electric current will be on disk 2 from " week along " flow direction " axle center ", and disk 2 will move in the direction of the clock under electrodynamic effect.
" one-way motors " of Fig. 2 is that 2 topology of the disk among Fig. 1 mapping (topological mapping) is deformed into a strip metal crawler belt 6, and allows crawler belt 6 another kind of organization plan of " rotation " between the N-S magnetic pole.If between "+", "-" two brushes, add a vdc from the outside, crawler belt 6 will move in the direction of the clock.Acyclic machine has many subforms.But they interosculate: 1) do not have " commufafor " (being commutator); 2) must carry out the electromagnetic induction of " cutting type " in the mode of " infinitely sending to ".
In the solid model of superincumbent two one-way motors, the cutting movement of " infinitely sending to " is that the lasting rotation by disk or crawler belt realizes.And among the present invention, the excitatory element of unidirectional DC motor is derived from into metal sheet palisade armature pattern.Like this, the magnetic road surface of rail just in time is " single magnetic pole stator " of " endless ", and the behavior of advancing of train just in time is exactly the electromagnetic induction motion of this unidirectional DC motor " cutting type " " infinitely sent to ".Can find out in the present invention, " driving " of train, " floating " two kinds of basic function, independently of one another onboard in the simplest mode, compatible each other on rail.
Why adopt metal sheet palisade armature rather than block of metal, be for fear of eddy current loss and make the electric current can rectangular distribution.Metal sheet palisade armature is preferably copper bar or aluminium row, but also can be to put into copper bar or aluminum strip in fluting, the groove on steel plate, forms at the both side ends short circuit with copper strips or aluminium strip then.
The Electronmotive Force F=BLI that is subjected to behind the metal sheet palisade armature current-carrying (B is a magnetic induction density, and L is the length of armature, and I is an armature current) just is being with train to travel forward.From the F=BLI formula as can be seen: L is a constant with ' conductor ' radical; When not adjusting " gap " big or small, B also is a constant.So the size of Electronmotive Force F is directly proportional with electric current I.Train was made accelerated movement before this under the effect of F; When the resistance of air rises to when equating with F with the speed of a motor vehicle, train enters at the uniform velocity travel condition.Obviously F is big more, and the vehicle velocity V when reaching state at the uniform velocity is just high more.So transferring electric current I promptly is accent power F; Accent power F promptly is speed governing degree V.
The size of electric current I is can continually varying, belongs to infinite speed variation so locate governing speed V.Under the contrast, the speed governing on a large scale of DC machine, than alternating current confidential simple and easy, make things convenient for manyly, much also economical.The speed governing of AC machine generally will realize by variable-frequency power sources.The mode of speed control of crosstalk resistance is inapplicable in this occasion in the wound rotor.Promptly used, also uneconomical.
It is stressed now to analyze car body.Analyze the stressed relation of floating outstanding state lower body earlier: towards the car working direction, among Fig. 3 and 4, power (as
The gap is (as δ
L, δ
R) subscript " L " expression " left side ", subscript " R " expression " right side ", trapezoidal " central plane " and ground-surface angle are θ, the inside inclination angle of normal of rail level was φ when a left side was curved, C is a body gravity, G is a car body gravity.On " central plane " of on the left side, the bottom of car body be subjected to perpendicular to the repulsion on surface be
Its upward component is f
LYTo right component is f
LXEqually, be subjected to perpendicular to the repulsion on surface on the face of the right " waist " be
Its upwards and left component be respectively f
RYAnd f
RXAs can be seen from Figure 3: the upward component of left and right repulsion is two equal-sized cocurrent and parallel power, they make a concerted effort just in time and car body gross weight G balance.And the horizontal component of left and right repulsion is equivalent and oppositely, their effect quite a pair of " pinching power ", and its effect is to make car body placed in the middle automatically: because if car body is taken back the gap delta on the left side then
LMust be less than the gap delta on the right
R, the repulsion on the left side must be greater than the repulsion on the right, and the horizontal component difference of the two will be pushed to the car body of taking back right-hand.When car body took over, then the horizontal component missionary society of repulsion pushed car body to left.This just makes car body in left and right direction has realized returning automatically.If car body is placed in the middle, the horizontal component difference of left and right sides repulsion just equals zero so.
See Fig. 4, when train entered bend, the gap of the outside (being centrifugal side) reduced, and outside repulsion increases automatically; The gap of inboard (entad side) then increases, and inboard repulsion reduces automatically.Repulsion is greater than inboard repulsion outside this moment, and the horizontal component of left and right sides repulsion is poor, and the necessary guidance force of turning will be provided.For prevent that train from centrifugal toppling being taken place in the bend scope, the normal of the rail level in bend zone still needs to do centroclinal dip, and this principle is identical with the bend design of conventional railway.
The invention has the beneficial effects as follows: the magnetic suspension train car body that is provided, the rail that cooperates car body to use, and comprise that the two high speed train technology is simple, cost is low but safe in utilization.
