| Abstract: |
| This study considers a superconducting electrodynamic maglev train of MLX01 type. The characteristics of the electromagnetic spring coefficient of a single bogie under different magnetomotive force(MF) of the superconducting coil and standard air gap (Sag) were explored. In view of the small electromagnetic damping, a passive damping control strategy and an active damping control strategy were designed to increase the electromagnetic damping force between the superconducting coil and ground coil. Combined with the coupling numerical model of a single bogie, the vibration characteristics of the bogie in different directions with different damping control strategies were studied when the Sag and MF were fixed. The results can provide important theoretical support for stable operation control of maglev trains. |
