The magnetic levitation technology, which performants better with support of linear motor than wheel-track train, gets rapid progress. Superconducting electrodynamic levitation (EDL) system technology is focused on because of its ultra-speed, heavy burden and low energy consumption. Based on the simulation of the magnetic levitation force and induced current of superconducting EDL system with finite element model, this paper analyses the influence of current, velocity, gap distance and balancing displacement (vertical distance of geometry center), explaining the results with circuit model. Besides, by simulating variety of flux of single coil system, the change of the magnetic levitation force and induced current gets explanation and supplies reference data for next optimization of parameters.
