Simulation and Optimization of High Temperature Superconducting Maglev Track Layout Based on Tilted Magnetized Magnets

Due to the absence of wheel-rail contact friction and the advantage of self-stable and self-guided levitation, HTS (HTS) maglev has enormous development potential and broad application prospects in the transportation field. At present, the Halbach-type track layout is commonly used for HTS maglev, with a single layout form, and the magnetic field above the track cannot be further improved. To further enhance the load-bearing capacity of the HTS maglev system, it is necessary to optimize the track layout. This paper proposes a tilted magnetization (TM) track layout type based on tilted magnetization magnets and compares the magnetic field distribution and levitation force of Halbach-type layout and TM-type layout through finite element simulation. The TM-type can effectively improve the amplitude of longitudinal magnetic induction intensity component and levitation force amplitude, with a maximum increase of 11.08% and 12.97%, respectively, which can effectively enhance the load-bearing capacity of HTS magnetic levitation systems. This paper provides theoretical support for the research of high-load HTS maglev technology.
