Study on the effect of permanent magnet guideway surface defect on the mechanical properties of multi-surface high-temperature superconducting permanent magnet levitation system with halbach-type guideway

Abstract

Abstract The purpose of this study is to discuss the effect of defects on the mechanical properties of halbach-type guideway surfaces in high-temperature superconducting permanent magnetic levitation systems with single-surface superconductor distribution versus multi-surface superconductor distribution. The study models the high-temperature superconducting permanent magnetic levitation system based on Maxwell’s system of equations and compares it with the experimental data to obtain the variation curve of the levitation force of the levitation system under ideal conditions. Through numerical simulation and data analysis, it is found that the levitation force and guiding force of the high-temperature superconducting permanent magnetic levitation system will regularly decrease with the expansion of the defects, which will lead to the reduction of the system’s load-carrying capacity and stability. These findings are of great significance for the design and application of high-temperature superconducting magnetic levitation systems, and provide theoretical support and technical guidance for the practical application of high-temperature superconducting magnetic levitation systems.
