Description
Technical field
The present invention relates to vacuum train technical field, especially a kind of vacuum train position adaptive controller.
Background technology
Magnetic suspension traffic is a kind of rail traffic of no Wheel Rail Contact.Maglev vehicle has several different classification sides at present
Method.According to the difference of suspension theory, magnetic suspension train can be generally divided into electrodynamics suspension type（EDS）, electromagnetic suspension type（EMS）；
According to the difference of magnet, and normal conductivity type, superconduction type, permanent-magnet type and hybrid magnet type can be divided into；Different according to speed again can
To be divided into medium-and low-speed maglev（Less than 200km/h）And high-speed magnetic floating（500km/h）；It is same to be divided into straight line according to the difference of propulsion mode
Walk motor-type and linear induction type.
The suspension control assembly of existing vacuum train is provided at the lower part of vacuum pipe and train, once train is in high speed
Or run in the case of ultrahigh speed, it is easy to so that the buoyancy that train generates is more than its own gravity, easily and vacuum tube so as to cause train
Road collision or out of control, operation is extremely unstable, substantially reduces safety coefficient.
Invention content
A kind of safety coefficient height is provided the purpose of the present invention is overcoming the above-mentioned insufficient of the prior art, stable is true
Empties train position adaptive controller.
The technical scheme is that：A kind of vacuum train position adaptive controller, including vacuum pipe and be located at
Train in vacuum pipe, train is by magnetic levitation in vacuum pipe；The top of vacuum pipe and train is equipped at least one
Group generates the limiting section of repulsion.
Said program has the following advantages：When the speed of service quickly, such as enters high speed or superelevation to train in vacuum pipe
When fast state, as long as the buoyancy of train floats upwards more than its own gravity, the limiting section by being generated repulsion incudes, Jiu Huifang
Only the top of train and vacuum pipe bump against, closer to limiting section, the repulsion of generation is bigger, to by train stable suspersion in
In vacuum pipe, it will not be contacted with vacuum pipe, greatly improve safety coefficient, make train stable operation in vacuum pipe.
As long as the limiting section of the present invention can generate the device of repulsion or structure is within the scope of the invention.
Further, the limiting section on the train is magnet.
Further, the limiting section on the train is permanent magnet and/or electromagnet.Limiting section on train can be permanent magnetism
Body is combined arrangement, such as the side setting permanent magnet at the top of train with electromagnet, and electromagnet is arranged in the other side；In another example permanent magnet
It is staggered with electromagnet.
Further, the limiting section on the vacuum pipe is when keeping determining deviation movement with magnet, to generate induced current
And form the repulsion tablet in magnetic field.
As long as the tablet of the present invention can interact with magnet and generate induced current, all in protection scope of the present invention
It is interior.The shape of repulsion tablet can be arc, linear type or other shapes.Repulsion tablet on vacuum pipe can be more
It is a, it can be alternatively arranged between multiple repulsion tablets or close-packed arrays, can also be part interval, part close-packed arrays；Very
Repulsion tablet on vacant duct can also only there are one, the length along vacuum pipe is arranged.
Further, the repulsion tablet is aluminium or copper tablet.Aluminium tablet and copper tablet all have higher lead
Electric rate, and attraction will not be generated with magnet.
The operation principle of the present invention is that：Repulsion tablet of the magnet above it on train keeps a determining deviation to move
When, repulsion tablet generates induced current and forms magnetic field, by the Lenz's law magnetic field with magnets magnetic fields polarity on the contrary, the two phase
Interaction generates a downward repulsion to magnet, and train is avoided to generate collision or out of control.
Further, the limiting section is set to the top of vacuum pipe and train.
Further, the limiting section is set to vacuum pipe and the top of train corresponds to both sides.Being symmetrical arranged can be further
Improve the stability of train operation.
In the present invention, the position of limiting section can be arbitrarily arranged, as long as set on the top of vacuum pipe and train.
Further, when the levitation gap between the train top and vacuum pipe is less than target gap, limiting section just generates
Repulsion acts on.Why the setting of limiting section will meet above-mentioned condition, be in order to ensure train is under high speed or ultrahigh speed environment
Stable operation.
Further, the lower part of the inner wall lower of the vacuum pipe and train is equipped with provides suspending power and guiding force for train
Magnetic levitation component.
Further, the inner wall bottom of the vacuum pipe is equipped with linear motor stator electric, and train is equipped with fixed with linear motor
The opposite rotor of son.Linear motor is used to provide guiding force for train, drives train operation.Rotor is supported by magnetic suspension, is made
The gap for remaining certain between rotor and stator is obtained without contacting, this eliminates the need for the contact frictional resistance between stator and rotor.
Further, the lower part of the vacuum pipe is equipped with tablet, and train is equipped with the permanent magnet opposite with tablet.Row
In the process of running, permanent magnet provides suspending power to vehicle by forming opposing magnetic field between tablet, for train.Tablet can be
Aluminium tablet, copper tablet etc..
Beneficial effects of the present invention：（1）The limiting section that repulsion is generated by setting can make train steady in vacuum pipe
Fixed operation, not will produce collision or out-of-control phenomenon, greatly improves safety coefficient；（2）Suspension between train top and vacuum pipe
When gap is less than target gap, limiting section just generates repulsion effect, is the normal operation that limiting section influences train in order to prevent, i.e.,
The constraint in unrestricted position portion when train normal operation when only train soon collides vacuum pipe, just generates repulsion effect, both
Safety is improved, and reduces power consumption.
