Investigation of electromagnetic force parameters of new generation PM/HTS-aluminum rail electrodynamic (EDL) maglev transportation systems by numerical and experimental methods

In this doctoral study, a modular aluminum-rail-based electrodynamic levitation (EDL) system was developed, capable of interacting with various magnetic field sources including permanent magnets (PM), high-temperature superconductors (HTS), and coil-based configurations. The system enables detailed investigation of lift and drag forces through both numerical (via COMSOL Multiphysics) and experimental methods. A high-speed experimental setup, simulating speeds equivalent to 320 km/h, was constructed and equipped with SCADA-integrated PLC control, multi-axis force sensors, cryogenic cooling, and precise motion tracking systems. Measurements taken at varying speeds and levitation gaps were compared with theoretical and numerical models to validate the system. Key contributions include the validation of passive force generation mechanisms (without active field excitation), optimization of slotted rail geometries, analysis of HTS flux pinning effects on levitation, and the design of a modular test infrastructure. Overall, this study provides original and comprehensive data supporting the advancement of innovative and domestically developed Maglev technologies from both scientific and engineering perspectives.
