LEVITATION CHARACTERISTICS OF MAGNETICALLY SUSPENDED VEHICLES UTILIZING CONTINUOUS CONDUCTIVE SHEETS

In the loop-type track, the magnetic field produced by ground coils is not uniform and therefore the lift force fluctuates as the train moves and the magnetic flux of the superconducting magnet fluctuates with time. Further, the manufacturing and installation cost of the ground coil is very expensive. To solve the difficulty an intensive study is being carried out in other countries on the sheet-type track which consists of continuous conductive sheets of aluminum or copper. In these analyses, it has usually been assumed that the sheet is infinitely or semiinfinitely wide. In this paper, the author replaces a ground sheet with finite width by a number of conductors with square cross section and arranges them in the running direction. Self- and mutual inductances of the conductors are taken into account in calculating the levitation characteristics. Calculated levitation characteristics of the sheet-type track are compared with those of the loop-type track. It is found that there is a certain finite sheet width which maximizes the lift force.
