Description
Technical field
The present invention relates to magnetic levitation technology field, maglev trolley demonstration is hung upside down in more particularly to a kind of double superconductions
System.
Background technology
Magnetic levitation technology just proposes electromagnetism early in nineteen twenty-two German engineer Herman Ken Peier and hangs originating from Germany
Floating principle, and the patent for having applied for magnetic suspension train in 1934.After 1970, with world industry national economic strength
Continuous reinforcement, to improve traffic capacity to adapt to the needs of its economic development, Germany, Japan, the U.S., Canada, method
The developed countries such as state, Britain start to prepare the exploitation for carrying out conductivity magnetic levitation transport system in succession.Nineteen twenty-two, German Herman agree to wear
The electromagnetic suspension principle that you propose to come in 30 or 40 years in past, and magnetic levitation technology either vehicle performance still runs control
Technology, most problems of technological layer have all been resolved, many equipment of development reached it is originally envisaged that technical merit.
The development of superconductor technology and the raising of device manufacturing process and system Construction level, make the application of magnetic levitation technology
Ability has obtained faster promotion.According to coil-conductor attribute, magnetic levitation technology can be divided into normal conductivity type and superconduction type；According to suspension
Principle magnetic levitation technology can be divided into electromagnetic suspension system (EMS) and electrodynamics suspension system (EDS).From principle, magnetic levitation technology
Can be divided into/often lead two kinds of Main Patterns of+EMS0 (often leading magnetic attraction) and/superconduction+EDS0 (superconduction magnetic expelling type).The TR technologies of Germany
Using/often lead+EMS0, and ML technologies use/superconduction+EDS0 of Japan, they represent at present respectively compares for two kinds in the world
Close to the levitated transport technology of realistic scale
Projecting magentic suspension demonstrating system is exactly that the principle of superconduction is utilized, and traditional projecting magentic suspension demonstrating system is using single
Superconducting block is enclosed in small vehicle model by superconduction model, gives superconducting block liquid nitrogen cooling, after superconducting state is reached, trolley absorption
On permanent magnetic guideway, a kind of projecting state is formed.But since trolley is by the magnetic suspension suction of single side superconduction, it can not ensure
