Performance Evaluation of Superconducting Electrodynamic Suspension for Hyperloop Using Static Experiments

The Hyperloop is expected to surpass the speed limits of conventional ground transportation by minimizing air drag and friction resistance inside a vacuum tube, necessitating a stable magnetic levitation system. Among the various levitation methods being considered, electrodynamic suspension (EDS) combined with superconducting magnets (SCMs) capable of achieving a large airgap appears promising, as it can reduce infrastructure costs and enhance the Hyperloop's competitiveness. Although many studies have explored the use of SC-EDS in the Hyperloop, validating its performance at ultra-high speeds is challenging due to the need for a long test-bed, which consumes significant time and resources. This research aims to indirectly evaluate the highspeed performance of SC-EDS through static experiments. Magnetic flux density and levitation force of SCMs were measured using static experiments, and the performance of SC-EDS was assessed indirectly by calculating the induced current based on the experimental results. Additionally, each result was validated by comparing it with the numerical analysis result.
