Detailed description of the invention
Below with regard to the enforcement of this hydraulic permanent-magnetic magnetic-levitation traffic system, by compartment, guide rail, magnetic rodless piston hydraulic pressure
Cylinder, hydraulic control system and circuit design be illustrated with control, above five parts, the most interrelated, design,
During production, installation and debugging and maintenance work mutually, the existing division of labor has again cooperation, influences each other.
1) to implement a set of hydraulic permanent-magnetic magnetic-levitation traffic system, first have to clear and definite circuit, the volume of the flow of passengers (includes peak
The volume of the flow of passengers, the ebb volume of the flow of passengers and the normal volume of the flow of passengers), thus determine to run vehicle (often joint takes how many people, and several joints combine, or
Combination in what situations), distance between sites, road speed, down time etc..
2) principle of simulation test and Preliminary design
A) according to carriage body construction weight and load, required pushing away between selected strong magnets and strong magnets is calculated
Power and suction.
B) test out the thrust that can be generated by between selected strong magnets and strong magnets and suction, shielding will be taked
Measure, had both protected neighbouring ferromagnet unaffected, can improve again the mutual attractive force between Magnet and repulsive force.
C) shape of Magnet, size, variation relation between installation relation and magnetic flux are drawn.
Drawing: take the compartment box weight of how many people, carriage weight adds the total amount of passenger, with this kind of Magnet, uses
What shape and size, uses what kind of arrangement, needs how much Magnet to be suspended in compartment and passenger.Consider
Various factors.
D) drawing: passenger is few, suspending power is constant, has great remaining suspension power, in order to design suspension distance limit part
Structure, strength and stiffness.
According to above technical parameter, the shape of suspension magnet, size and arrangement on guide rail can be designed, design compartment
The shape of upper suspension magnet, size and arrangement.
Note during design, increase the area of correspondence direction between suspension magnet, be conducive to making compartment suspension magnet and guide rail
Keep bigger " contact " area between suspension magnet, be conducive to improving repulsive force.
Reference technique parameter: nd-fe-b magnet suction about can pick up other ferromagnetic objects of itself quality 640 times.(factory
Family is different, has a long way to go)
It is generally acknowledged that magnetic pole can produce magnetic field.Magnetic field intensity and magnetic pole produced by the size of magnetic pull and Magnet
Intensity is directly proportional: F=mH, and wherein m is magnetic pole strength, and H is magnetic field intensity, and magnetic field intensity produced by magnetic pole and the 3 of distance r
Power is inversely proportional to.So, hydraulic permanent-magnetic magnetic-levitation traffic system uses permanent magnet can control to the least gap, and
Can be with basicly stable constant.
E) calculate and simulation test goes out: carriage weight adds the total amount of passenger needs great power permissible in the case of suspending
Advance it to advance.Various factors to be considered.
F) according to above technical parameter, design hydraulic control system and the piston of magnetic rod-less piston cylinder.

There is above technical parameter, it is possible to carry out compartment, guide rail, magnetic rod-less piston cylinder, hydraulic control system
Devise.
3) design compartment and during guide rail it is noted that:
First determine the width of guide rail, then determine the width of two row's guideway levitation Magnet, then determine that on compartment, two rows suspend
The position installing width of Magnet and structure；
Second, determine the distance between guideway levitation Magnet and suspension magnet, i.e. array way, here primarily to protect
" contact " area that card compartment Magnet is total with guide rail Magnet.
The shape of suspension magnet, size and density on guide rail, the shape of suspension magnet, size and density on compartment, it is desirable to
No matter where compartment runs to, it is to be ensured that " contact " (having gap) area of compartment suspension magnet and guideway levitation Magnet,

4) design of hydraulic system thrust to be considered and speed (being determined by the flow of hydraulic system), the two technology
Parameter request can set change (special messenger certainly must be had to be responsible for) the most easily.
Noting: generally, the most each website is apart from equal；Each website need to arrange a set of little pump, oil connection,
Valve, in order to adjust the distance between two cars railway carriage or compartment.
If requiring that reaching speed the most random with bus runs, and needs each website to arrange a hydraulic system operation
Personnel；If train is all stood, average rate, run on schedule, then control in master station.
If website distance, it is possible to be designed between each website and website run the time equal, i.e. operate in distance
The longer compartment between website, its speed of service speed of service to be scaled up, arrive at a station within the identical time.This
Point, for hydraulic system, it is easy to accomplish.
The requirement that hydraulic control system vehicle to be guaranteed turns around.The circuit of Fig. 8 and Fig. 9 needs to be designed to rodless piston can
Turning, in fact, street does not has straight, and Rail Transit System circuit inherently needs to turn round.Certainly, a set of new product is developed
Always having the exploitation of some new spare and accessory parts, such design, the engineer typically being provided with designing research and development ability should complete.
5) all worked, preferably made minisystem dry run test.
Different units, different requirements, can design according to the concrete condition of oneself.
Suspension system during we analyze hydraulic permanent-magnetic magnetic-levitation traffic system from structure below, advance system
System and guidance system.
Suspension system uses a kind of permanent magnetism mutual exclusion type suspension system.
Suspension system in hydraulic permanent-magnetic magnetic-levitation traffic system is led by the two row's permanent magnets installed in orbit
Rail suspension magnet (22) produces active levitation thrust, the compartment suspension magnet (12) being arranged on car bottom produce driven suspension
Thrust, two thrusts interact, and compartment boosts suspension and creates conditions for ultra-low friction motion.Owing to permanent magnet cannot be single
Solely control the accurate hoverheight in compartment, it is therefore desirable to the compartment spacing and guidance aid (14) of suspension and the compartment spacing rolling of suspension
The hoverheight in compartment is any limitation as by wheel (15).It will be appreciated that the magnetic field intensity of permanent magnetic field becomes cube with the increase of distance
Attenuation relation, guideway levitation Magnet is the least with the distance controlling of compartment suspension magnet, and mutual thrust is the biggest, and distance phase
Difference is the least, and thrust will change very big, so, the distance of guideway levitation Magnet and compartment suspension magnet should control at one
Excellent distance, this distance should be determined by test.Limit owing to the compartment spacing and guidance aid (14) of suspension and compartment suspend
Position roller (15) can limit the hoverheight in compartment exactly, it is possible to reaches the purpose controlled.In order to adjust gap
Convenient, compartment suspension limited roller (15) suspends in compartment the installation form on spacing and guidance aid (14), it should design
Become adjustable.
Propulsion system in hydraulic permanent-magnetic magnetic-levitation traffic system is to utilize hydraulic system can produce huge thrust

The compartment slide block (17) of motion, compartment slide block magnetic send out ferrum (18) and compartment slide block roller (19), and it is to utilize permanent magnet heteropole
Attracting principle.
It is known that after compartment is suspended, just there is no any frictional force, if handed over for ordinary municipal track
Logical, the most quickly, in operation, air drag is the least for the speed of service, therefore, in this hydraulic permanent-magnetic magnetic-levitation traffic system
Load hundred people compartments a joint and only need the least power to promote, if the traffic compartment of a circuit typically a set of hydraulic system
Power be sufficient for drive rolling stock.But, hydraulic system need to be designed to can independently control between each website.
Piston area in the operating pressure of hydraulic system and magnetic rod-less piston cylinder determines what hydraulic system provided
Thrust, namely drives railway car onward impulse, and this power needs by piston Magnet in magnetic rod-less piston cylinder
And mutual attractive force that between compartment slide block Magnet (18), heteropole is attracting is delivered on compartment drive compartment to advance (33).From forever
Magnetic line of force distribution that Magnet heteropole is attracting is it is recognised that magnetic field between piston Magnet (33) and compartment slide block Magnet (18)
State of strength, the captivation between permanent magnet with positive direction as maximum, so the shape of piston Magnet and it in hydraulic cylinder
Installation direction and position, should by design and test determine, in the hope of obtain optimum efficiency；Setting of compartment slide block Magnet (18)
Meter, installation method are too.
The decay in magnetic field is designed the most particularly significant by the gap between piston Magnet (33) and compartment slide block Magnet (18),
Here by piston Magnet roller (34) and compartment slide block roller (19) to piston Magnet (33) and compartment slide block Magnet (18) it
Between gap be controlled, to guarantee that piston Magnet runs unimpeded at oil cylinder inner wall and compartment slide block outside oil cylinder.
Guidance system in hydraulic permanent-magnetic magnetic-levitation traffic system is attracting mainly by permanent magnet heteropole and " each
To automatically having an effect " principle because without interference with guiding between suspension magnet, the guiding in compartment, mainly lived without bar by magnetic
The piston Magnet of plug hydraulic cylinder determines, its running orbit just determines the working line in compartment；Additionally it is provided with on compartment
The compartment spacing and guidance aid (14) of suspension and compartment auxiliary guide roller (16) carry out mechanical assistance guiding.
Attracting mutual of heteropole between piston Magnet (33) and compartment slide block Magnet (18) in magnetic rod-less piston cylinder
Compartment not only can be promoted and move ahead by captivation, and it also has an effect, it is simply that by compartment slide block by the operation rail in compartment
Mark be limited in firmly with on the track of piston magnetic Railway transportation row in magnetic rod-less piston cylinder.We can do an experiment,
When two blocks of Magnet one are the most attracting, if they to be pulled open by you, by prevention, you pull open the suction between them；If you will be by
One of Magnet pulls to the left side of another block Magnet, and by prevention, you pull the suction between them to the left side；If you want
Pulling to the right, by prevention, you pull to the right again for they；Equally, they also can pull stoping you up and down, we
The referred to as principle of permanent magnet heteropole attracting " respectively to automatically having an effect ", the guiding in hydraulic permanent-magnetic magnetic-levitation traffic system
System utilizes this principle the most exactly.So, the running orbit of piston Magnet just determines the working line in compartment.
Compartment arranges the compartment spacing and guidance aid (14) of suspension and compartment auxiliary guide roller (16) carries out machine
The design that tool auxiliary guides belongs to conventional mechanical design, seldom illustrates at this.
