Numerical Simulation of Levitation Force and Drag Force of Superconductiong Electrodynamic Maglev Train

Nowadays high-speed growing economy puts forward the demand for high-speed transportation. Magnetic levitation (Maglev) train satisfies the demand with its advantages of highspeed, low loss, low noise, and environment friendliness. In electrodynamic suspension (EDS) system, high temperature superconducting (HTS) coils can be used as levitation magnets. HTS magnets can generate stronger magnetic field than conventional normal conductor magnets and provide larger levitation force to increase the load capacity of the Maglev train. In this paper, a full-scale numerical model of the Maglev train suspension module is built, and the process of levitation with velocity is simulated. The levitation force and drag force are calculated using the model, and the influence of different levitation heights on both forces are investigated. Moreover, the forces are also discussed on the tracks with different materials, such as copper and aluminum.
