Abstract

The invention discloses a novel permanent magnetic suspension high-speed rail which comprises a suspended train body, suspended train body permanent magnets, a power coil, a bridge roadbed, piers and permanent magnet tracks on a bridge.A permanent-magnet technology is utilized, wear and a high temperature are not caused to the high-speed rail, and thus the service life is prolonged.The two permanent magnets are repulsive to each other within the range of h1 and attractive to each other within the range of h2 when the two permanent magnets are of the same polarity and repulsive to each other; the situation is not consistent with repulsion of the same polarity of the coulombs law, and the magnitude of action force is not inversely proportional to distance.The two permanent magnets of the same polarity are repulsive to each other within the range of h1 when being opposite to each other in an inclined mode, at the moment, repulsive force exists not only in the vertical direction, in addition, force occurs in the horizontal direction, and the force exists only within the width of the permanent magnets just like Lorentz force and is side thrust.The side thrust is utilized, attractive force within the range of h2 is avoided, and permanent magnetic suspension can be combined.

Description

A kind of permanent magnet suspension high ferro
Technical field
The invention belongs to high iron field, be specifically related to a kind of permanent magnet suspension high ferro.
Background technology
Modern magnetic levitation technology is primarily referred to as electromagnetic suspension technology, is with current induced magnetic field on the basis of Coulomb's law, makes object suspend by the repulsion of multiple points or attraction.Necessarily generating heat with current induced magnetic field, the time one is long, will burn out circuit, will solve problem it is necessary to there is heat sink, makes electromagnetic suspension complicated, expensive.Make object suspend and also have approach, i.e. a permanent magnet suspension, make object suspend by the mutually exclusive of permanent magnet or attraction.It is simply cheap, does not expend energy environment protection.And permanent magnet suspension is denied.Because having individual grace to continue theorem, it is determined that permanent magnet suspension is impossible, so abroad seldom there being research, and China is because the development of rare earth permanent magnet has many people to study, and the Li Guokun such as Lanzhou CAS Institute of Physics establishes and scolds dianoetic, push and pull theory.The Qian Kunxi of Jiangsu University teaches gyroscopic theory etc..
Permanent magnet suspension, namely permanent magnet and track (by electromagnetic path or permeability magnetic material) repel each other and be maintained at notch center line can suspension operation, electromagnetism guiding can realize zero friction and run, and machinery is to rubbing close to zero.
It is energy-conservation that permanent magnet suspension is applied in traffic advantage, and its resistance coefficient is about the 1/10 of resistance to rolling, with automobile energy consumption than for 1:10 in the 100km/h speed of service.Permanent magnet suspension traffic has the same safety, permanent magnet suspension height to be that a kind of free and stable being operated in certain interval approximate spring stress state suspends with rail transit.Electromagnetic suspension (such as Shanghai suspension traffic, Japan's superconductive suspension train scheme) is unstable suspension.The control technology leaning on complexity realizes suspending, and cannot guarantee that never loss of excitation, permanent magnet suspension can realize never loss of excitation forever without ensureing even if controlling to be made to improve very much.Permanent magnet suspension transit equipment structure is exactly that electromagnetic path changes magnetic suspension high-tech exactly with car body permanent magnetic strip assembly, permanent magnetic suspension technology innovation, high manufacturing cost, in high precision difficult enforcement become general technology, and low manufacturing cost is easily implemented big with penetration and promotion.
The principle of magnetic suspension train is not abstruse.It is the character using Magnet " same sex is repelled each other, and there is a natural attraction between the sexes ", makes Magnet have resistance gravitational ability, i.e. " magnetic suspension ".This to " magnetic suspension " principle is used on rail transportation system by scientist, makes train completely disengage from track and the traveling that suspends, and becomes " without wheel " train, time scooter hundreds of kilometer more than.Here it is so-called " magnetic suspension train ", it is also referred to as " maglev vehicle ".
Owing to Magnet has the same sex to repel each other and there is a natural attraction between the sexes two kinds of forms, therefore magnetic suspension train also has two kinds of corresponding forms: a kind of is utilize Magnet principle of same-sex repulsion and the electromagnetism that designs runs the magnetic suspension train of system, it utilizes the magnetic field of superconductor electric magnet formation on car and track to reach the standard grade and enclose produced mutual expelling force between the magnetic field formed, and makes the railway of car body suspension operation;Another kind of then be utilize Magnet principle of opposite sex attraction and the electric power that designs runs the magnetic suspension train of system, it is to install Magnet at vehicle bottom and both sides reversing top upwards, set reaction plate respectively with semi-girder beneath portions and sense steel plate above T-rail, control the electric current of electric magnet, make to keep between electric magnet and guide rail the gap of 10 15 millimeters, and make the repulsive force of guide rail steel plate and the gravitational equilibrium of vehicle, run so that car body is suspended on the guide pass in track.Magnetic suspension train is compared with current bullet train, there is many unrivaled advantages: owing to magnetic suspension train is to travel on track, between guide rail with locomotive, be absent from contacting of any reality, become " without wheel " state, therefore it is examined almost without rubbing between wheel, rail, speed per hour is up to hundreds of kilometer;Magnetic suspension train reliability is big, maintenance is easy, cost is low, its energy resource consumption be only the half of automobile, aircraft 1/4th;Noise is little, and when magnetic suspension train speed per hour reaches more than 300 kilometers, noise only has 65.6 decibels, just corresponds to a people and speaks loudly, also less than the sound of vehicle travels;Owing to it is with electricity for power, waste gas will not be discharged along the line at track, pollution-free, it is a kind of genuine green traffic instrument.
The applicant establishes thruster theory after applying for magnetic suspension bearing patent in 15 years, it is achieved thereby that permanent magnetic suspension technology: two permanent magnet same sexes exclude each other time just relative within the scope of h1, attract each other within the scope of h2.It does not meet the same sex of Coulomb's law and repels mutually, and the size of active force is not more and square being inversely proportional to of distance.During two same sex permanent magnet monoclinic phases pair, excluding each other within the scope of h1, it has repulsive force not only in the vertical direction this moment, also occurs a power in the horizontal direction, grows power such as Lip river logical sequence, and this power only exists in the width of permanent magnet own, and this power is side-thrust.Side-thrust and the captivation avoided within the scope of h2 is used namely to be combined into permanent magnet suspension.
