Abstract: High-speed superconducting suspension train adopts electrodynamic suspension method, which has
advantages in areas of high-speed and ultra-high-speed due to large suspension height and without suspension control. The
parametric analytical calculation model of three-dimensional electromagnetic force in superconducting coils located in one
side of the bogie is established by adopting dynamic circuit theory based on the structure parameter of Yamanashi test train
in Japan. The simulated results were compared with the experimental values of Yamanashi test line, the error was validated
less than 10%. By this analytical model, the influence of length and height of the suspension coil on the average value and
ripple of three-dimensional electromagnetic force was analyzed. It was found the induced current, average value and the
ripple of the electromagnetic force are increased along with the increase of suspension coil length and the suspension force
and the guidance force first increase and then decrease along with the increase of the suspension coil height. The structural
of the suspension coil were optimized under the requirement of increased operating speed.
