In previous research, a two-dimensional numerical model based on Newton’s second law and Maxwell’s equations was developed to analyze the dynamic behavior of superconducting maglev systems. Studies showed that vibration and drift phenomena will occur in the vertical and lateral directions triggered by external disturbances, resulting in a change in the levitation point and even instability. In this paper, a numerical analysis is further carried out to alleviate these situations. The dependence of the drifts of vertical and lateral vibration centers of the levitated body upon system material parameters, such as the magnetization of permanent magnets and the critical current density of superconductor, is studied in terms of a power law model. In addition, the influence of the configuration of permanent magnets on the dynamic stability is analyzed.
