Conference Paper Description

The levitation force between the magnetic field captured by the high temperature superconductor (HTS) and the magnetic field of permanent magnet rail is important for the high temperature superconductor magnetic levitation vehicle, which can guarantee the self-stabilizing suspension and directly determine the capacity of the vehicle. In this paper, the finite element method is used to analyze the levitation force. The captured magnetic field of HTS is obtained by way of calculating the magnetic field at the field cold height. The levitation force between HTS bulk and permanent magnet is calculated by the captured magnetic field and low magnetic permeability, which is validated by way of experiment. Based on above method, the levitation force between multiple HTS bulks installed on magnetic levitation vehicle and the permanent magnet rail is calculated. By designing the sandwich structure consisted of multiple HTS bulks and permanent magnet rail, the levitation force of high temperature superconductor magnetic vehicle can be effectively increased, which provides the basis of force characteristics for the dynamic modeling and simulation analysis.
