Description
Technical field
The utility model patent relates to a kind of automobile-used high temperature superconducting magnetic suspension system.
Background technology
Magnetic-levitation traffic has at present become the inevitable requirement of railway development, is particularly useful for the transportation of city, tourist attractions short-distance and medium-distance.With regard to the magnetic-levitation vehicle of having developed, generally there are three types by the type of using magnet.At first first kind is permanent magnetic levitation train.The principle that there is a natural attraction between the sexes realizes to utilize the same sex to repel each other, and generally permanent-magnet clusters is attached together the suspension that the train that fits over track and motion is realized train.DaLian, China permanent-magnet compensation formula levitated vehicle " No. one, China " uses rare earth permanent-magnetic material, the vertical suspension not consuming electric power, and suspending power is strong, magnetic field sensing electromagnetism guiding.Shanghai Normal University also develops similar small-sized magnetically supported vehicle scheme.But the utilization of vehicle-mounted permanent-magnet material must increase the weight of car body weight, and it is high that magnetic screening requires to want.Its guiding (side direction) stability is controlled realization by a series of sensor and control structure fully simultaneously, complex structure, guiding poor stability.Stop of the research of vehicle-mounted permanent magnetism-permanent magnetism magnetic suspension abroad mostly in field of track traffic.
Second kind is called the electromagnetic suspension car, can be divided into electromagnetic attaction formula (EMS) and magnetic repulsion type (EDL).
Electromagnetic attaction formula magnetic suspension method is to utilize the attractive force between vehicle-mounted electromagnet (placing the below of suspension car body usually) and the ferrimagnetism track to realize suspending.As the normal conductive magnetism aspiration-type train of the German Transrapid series and the HSST series of Japan, the 30km test wire that the German Transrapid technology of calendar year 2001 China's introduction is built in Shanghai.The suspension spacing was limited to about 10mm usually when this mode adopted normal conducting magnetic iron, must a series of sensors and corresponding current feedback system control hoverheight.And the current capacity of vehicle-mounted conventional conductor magnet is poor, and energy consumption greatly very easily problem such as heating makes this magnetic suspension system design complicated cost height.Even utilize superconducting wire to replace conventional conductor, also can only under the situation of direct current energising, solve and reduce the big problem of energy consumption.Because the introducing of cryogenic system and the uncontrollability of superconducting wire A.C.power loss must have been brought more practical problems, improve poor stability etc. as cost.
The maglev representative products of magnetic repulsion type is that Japan is in LSM, the ML of beginning in 1972 and the research of MLU series.Adopted the low-temperature superconducting coil, on December 21st, 1979 the ML-500 magnetic suspension train realized 517km/h the most at a high speed.The U.S. in 2006 uses the superconduction meeting and has issued the message that substitutes the successful operation of part low-temperature superconducting coil with high-temperature superconductor.But these record-breaking pilot systems can not be avoided the configuration of large-scale fefrigerator, and the big maintenance difficulty of dimensional weight increases.Vehicle-mounted magnet does not produce complete magnetic circuit, and magnetic shielding device needs to increase, and makes the complexity of magnetic repulsion type magnetic suspension system.This as can be seen electromagnetic type magnetic suspension system is quite complicated, restricts in several factors.
The high temperature superconductor magnetic levitation vehicle of the vehicle-mounted high-temperature superconducting block form that the third is feasible, it forms principle is to utilize the strong pinning ability of high-temperature superconducting block.This inactive mode that does not need artificial controlled reset suspends and has brought the stable and car body of bigger magnetostatic energy not have flux leakage, and has guaranteed stable.Compare other two kinds of magnetic suspension trains, vehicle-mounted suspension scheme has advantages such as ancillary systems such as simple structure, no magnetic screening or control, cryogenic system are simple.From the angle of system, this high-temperature superconducting maglev train is the scheme that has DEVELOPMENT PROSPECT.What high temperature superconductor magnetic levitation vehicle of having developed at present or laboratory vehicle adopted is that vehicle-mounted pure high-temperature superconducting block is realized the train steady stability above tracks of permanent magnetism, smooth running under the driving of linear electric motors.But be subject to existing high-temperature superconducting block suspension property and development ability, make the suspending power of magnetic suspension train and guiding stability be still waiting further raising.
