Mode is applied to elaborate the utility model.
Preferred embodiment of the present utility model provides a kind of method for improving vehicle magnetic suspension performance, including following step
Suddenly：S10：The c-axis of the superconducting block 31 that the vertical component in the magnetic field of track accounted at leading position are vertically arranged, make the magnetic of track
The c-axis of the superconducting block 31 that the horizontal component of field is accounted at leading position are horizontally disposed with；S20：Vehicle is set to be subtracted in vertical direction
Shake function.The utility model makes direction of the c-axis setting direction just with the magnetic field of track 10 parallel by putting superconducting block 31,
So as to improve the suspending power of vehicle, and smooth-ride is enabled the vehicle to by the shock-absorbing function increased on vertical direction.
In high temperature superconducting magnetic suspension system, the suffered suspending power of superconducting block 31 is close with the size and gradient of external magnetic field
It is related.Wherein, the graded of external magnetic field determines the induced-current size inside superconducting block 31, both induced-current and external magnetic field
Final Lorentz force is determined, suspending power and guiding force correspond to the vertically and horizontally component of Lorentz force respectively.Therefore, in order that
Superconducting block 31 has given play to optimal magnetic suspension performance, it is necessary to combining form according to bulk provides a rational external magnetic field knot
Structure.Fig. 2 and Fig. 3 sets forth the Distribution of Magnetic Field at the Flux distribution and surface 15mm of experiment Halbach tracks of permanent magnetism,
As can be seen from the figure vertical magnetic-field component Bn is maximum at permanent magnet pole position, tracks of permanent magnetism by-level magnetic-field component Bt
It is maximum.As shown in figure 4, at position of magnetic pole, (the c-axis and magnetic of superconducting block 31 when the ab faces of superconducting block 31 are just put to tracks of permanent magnetism
Field direction is parallel) best results；But in tracks of permanent magnetism middle position, magnetic flux line is nearly all i.e. superconducting block in the horizontal direction
31c axles are in 90 ° of angles with magnetic direction, and now the ab faces with more high current density do not act on fully with external magnetic field, such as Fig. 5
Shown, when the c-axis placing direction of superconducting block 31 is identical with outer magnetic field direction, action effect will more preferably.
In order to verify this design philosophy, to the superconducting block 31 of different pose patterns various location magnetic suspension performance
It is carried out checking.In order to describe conveniently, crest, the vertical magnetic of orbit centre are called at the magnetic pole vertical component magnetic field maximum
The minimum place of field component is referred to as trough, and trough is also the maximum place of horizontal component ofmagnetic field.Surveyed using high-temperature superconducting magnetic levitation
The suspending power that the superconducting block 31 for putting (conventionally form) and vertical display to level at crest and trough is put in trial assembly is tested.
Implement checking display when the level of superconducting block 31 is put, suspending power is more than suspending power at trough at crest；And superconduction
During 31 vertical display of block, suspending power is more than suspending power at crest at trough；And at trough vertical display the suspending power of superconducting block 31
The level of being greater than puts the suspending power of superconducting block 31.Experimental result again demonstrates the horizontal pose pattern of superconducting block 31 at crest and hangs
Buoyancy is optimal, while explanation can be to improve it to hang when changing the superconducting block 31 that level at former wave trough position is put into vertical display
Buoyancy energy.It is 32mm that the width occupied just to tracks of permanent magnetism is put in view of the level of superconducting block 31, and after vertical display, this width
It is changed into the height 13mm (as shown in Figure 5) of original superconducting block 31, i.e., under same space, superconducting block 31 at least can be with vertical pendulum
Put 2 pieces.Principle according to approximate superposition can extrapolate suspending power during 2 pieces of superconducting blocks 31 of vertical display.At wave trough position,
When 2 pieces of superconducting blocks 31 of vertical display, the maximum suspending power at test height 10mm is approximately：104.6N × 2=209.2N,
Much larger than the 92.1N that level is put.This explanation uses vertical display form at trough, makes the superconduction with more high current density
Block 31ab faces fully act on track tangential component magnetic field, and the suspendability of superconducting block 31 also has the very big rising space.
The cold height 30mm superconducting blocks 3131 of 1, table maximum suspending power and guiding force at different disposing ways and test position
Note：(× 2) during vertical pendulum is let pass in table are represented when occupying same width, with two pieces of vertical display, therefore can be multiplied
With coefficient 2.
Table 1 provide typical condition of work (the cold height FCH30mm in field) under superconducting block 31 in different disposing ways and test
The maximum suspending power of position, improves its magnetcisuspension buoyancy by changing the arrangement of superconducting block 31c direction of principal axis as can be seen from Table 1
Can method is feasible and effect is significant.The level of superconducting block 31 put at wave trough position after becoming vertical display, superconducting block
The approximate lifting obtained from 92.1N → 209.2N is increased 2.27 times by 31 suspending power.Therefore, in actual applications, can be with root
According to actual demand, the c-axis direction arrangement of superconducting block 31 is designed with reference to the structure and its Distribution of Magnetic Field of tracks of permanent magnetism, with the side of realization
Case target.
As shown in figure 1, preferred embodiment of the present utility model discloses a kind of high-temperature superconductor magnetcisuspension based on the above method

Vehicle is set to carry certain load condition downward driving, buffer gear 40 is for slowing down the motion of vehicle in the vertical direction to buffer
The vibrations that vehicle occurs in the process of moving.Wherein, magnetic suspension mechanism specifically includes track 10, low-temperature (low temperature) vessel 20 and multiple and surpasses
Guide block 31, low-temperature (low temperature) vessel 20 is arranged on the surface of track 10, and multiple superconducting blocks 31 are placed in low-temperature (low temperature) vessel 20 and along track 10
Width arrangement and formed superconducting block layer 30, it is of the present utility model to it is critical only that：The vertical component in the magnetic field of track 10
The c-axis of the superconducting block 31 of leading overlying regions are vertically arranged, the leading overlying regions of the horizontal component in the magnetic field of track 10 it is super
The c-axis of guide block 31 are horizontally disposed with.The utility model by putting superconducting block 31, make c-axis setting direction just with the magnetic of track 10
The direction of field is parallel such that it is able to improves the suspending power of vehicle, and enables the vehicle to steady row by increasing buffer gear 40
Sail.
Preferably, track 10 is unimodal magnetic field structure or the multimodal magnetic field structure in width arrangement.
For when high temperature superconducting magnetic suspension system is applied to vehicle, the magnetic force between track 10 and superconducting block 31
Although effect can provide partial buffer effect for the vibrations of vehicle, the vibrations to farthest reduce vehicle also need list
Only reload buffer mechanism 40, this is also the reason for buffer system is introduced high temperature superconducting magnetic suspension system by the utility model.
The structure or composition of the buffer gear 40 with cushioning effect can have various, such as damping spring, i.e., hold in low temperature
Damping spring is set between device 20 and vehicle frame 50, elastic deformation is occurred when by mechanical force using damping spring and vehicle is risen
To cushioning effect.But there is the defect at least two parties face in damping spring：One is, damping spring can be because for during vibrations
Substantially prevent vehicle vertical from moving downward and play obvious cushioning effect, and transported upwards for the vehicle vertical during vibrations
When dynamic, prevention because of damping spring to the upward motion of vehicle vertical is indifferent, and (damping spring compression effect is good, and tension effect
Difference) and the cushioning effect that plays is not strong；Two are, damping spring easily fails because frequently there is elastic deformation, or even fatigue
Destruction, and then cause cushioning effect to weaken even failure.
To improve the damping performance of vehicle, it is excellent that a preferred embodiment of the present utility model provides a kind of damping effect
Buffer gear 40, simultaneously combined shown in Fig. 1 such as Fig. 6, specifically, buffer gear 40 includes being fixed on the cylinder on the top of low-temperature (low temperature) vessel 20
Body 41, it is arranged in the chamber of cylinder body 41 and by chamber respectively into upper chamber's (hydraulic medium is provided with upper chamber) and lower chambers
The piston 42 of (bottom chamber is provided with hydraulic medium) and upper end are fixed on vehicle frame 50, and cylinder body 41 and piston 42 are stretched into lower end
The piston rod 43 of connection, upper chamber and bottom chamber are respectively arranged with damping spring 47 and lower damping spring 44.Wherein：Piston
Entrance and exit is equiped with 42 and corresponds to the first check valve 45 and entrance and exit connected with upper chamber and lower chambers respectively
The second check valve 46 connected with lower chambers and upper chamber is corresponded to respectively, and sets the conducting pressure condition of the second check valve 46
It is set to when piston rod 43 and piston 42 bear the gravity of whole vehicle, the second check valve 46 is worked as and held still in closed mode
When the power received is numerical value a certain more than vehicle weight, the second check valve 46 is turned on, and the turn-on condition for the first check valve 45 can
To be set as any pressure value.
The reason for above-mentioned buffer gear 40 can play cushioning effect be：When vehicle in the vertical direction shakes
When, the hydraulic medium of bottom chamber has certain pressure because bearing the gravity of whole vehicle, the second check valve on piston 42
46 close because being not up to turn-on condition, and the first check valve 45 is because with return-stopping function, so that the hydraulic pressure of bottom chamber is situated between
Matter cannot enter upper chamber by the first check valve 45 and the second check valve 46, so that the in the vertical direction of piston rod 43 is protected
Hold motionless, vehicle smooth-ride in the horizontal direction.When because of certain reason (as track 10 lays out-of-flatness) lower section of cylinder body 41
When running gear (such as low-temperature (low temperature) vessel 20 and superconducting block 31) in the vertical direction shakes, when running gear is unexpected straight up
During motion, the hydraulic medium of bottom chamber is subject to the extruding of piston 42 and pressure rise, when pressure rise to the second check valve 46
Turn-on condition when, the second check valve 46 is turned on, and the hydraulic medium of bottom chamber enters upper chamber, cylinder by the second check valve 46
Body 41 is moved upwards with running gear, and running gear and cylinder body 41 will not upwards be transported with piston 42, piston rod 43 and vehicle
Dynamic or piston 42, piston rod 43 and vehicle are slowly moved upwards, so as to reach the purpose of buffering, when running gear is unexpected
When moving straight down, hydraulic medium in upper chamber is subject to the extruding of piston 42 and pressure rise, when pressure rise to first
During the turn-on condition of check valve 45, the first check valve 45 is turned on, and the hydraulic medium in upper chamber is entered by the first check valve 45
Lower chambers, cylinder body 41 is moved downward with running gear, and running gear and cylinder body 41 will not be with piston 42, piston rod 43 and cars
Move downward or piston 42, piston rod 43 and vehicle are slowly moved downward, so as to reach the purpose of buffering.
Above-mentioned buffer gear 40 utilizes hydraulic medium under the control of the first check valve 45 and the second check valve 46 in epicoele
Flowed between room and lower chambers, so that cylinder body 41 forms relative motion with piston rod 43, and then realize the buffering to vehicle, this
Plant fluid pressure type damping modes has the characteristics of buffering soft compared to the damping modes of damping spring, it is often more important that in the absence of elasticity
The defect of failure, and the damping spring defect bad to the vehicle bumper effect moved straight up can be overcome.
Turn-on condition for the second above-mentioned check valve 46 can be construed to：When vehicle even running, second is unidirectional
Valve 46 must be remained off, and the hydraulic medium of lower chambers is supported vehicle, and it is unexpected to work as running gear
Upwards during motion, the extruding lower chambers of piston 42, when now the pressure of the hydraulic medium of bottom chamber is higher than vehicle even running
Pressure, the turn-on condition of the second check valve 46 is arranged in elevated a certain pressure value will cause running gear upward
When moving to a certain degree, the second check valve 46 is turned on.
From the explanations above as can be seen that turn-on condition set by the second check valve 46 closer to vehicle even running at present
The pressure of the hydraulic medium of chamber, the buffering effect of buffer gear 40 is better.
Further to improve the damping effect of buffer gear 40, in a preferred embodiment of the present utility model, epicoele
