Levitation characteristics of magnetically suspended vehicles utilizing continuous conductive sheets
In a magnetically levitated railway system with superconducting vehicular magnetic coil, short-circuiting ground coil, and a 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. The sheet-type track consists of continuous conductive sheets of aluminum or copper. The levitation characteristics of the sheet-type track have been analyzed so far by directly solving Maxwell's equation or by replacing the sheet current by an image current. In these analyses, it has usually been assumed that the sheet is infinitely or semiinfinitely wide. Until now, the levitation characteristics of a sheet-type track with finite width have been analyzed little. An analysis is given in which a ground sheet with finite width is replaced by a number of conductors with square cross section arranged 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.
