Multi-degree-of-freedom magnetic suspension damping device capable of resisting sea wave impact

The invention discloses a multi-degree-of-freedom magnetic suspension damping device capable of resisting sea wave impact. The multi-degree-of-freedom magnetic suspension damping device comprises a shell, a bearing table, a first permanent magnet, a second permanent magnet, a magnetic induction coil group, an annular magnet and an external wiring part, the shell is in an uncovered cylinder shape, a first permanent magnet is fixed in a circular groove in the bottom of an inner cavity of the shell, 12 magnetic induction coil sets are evenly distributed on the side wall of the inner cavity of the shell in the circumferential direction through installation interfaces, and an external wiring part is arranged on the outer side wall of the shell and connected with an external power source. A second permanent magnet is fixed in a circular groove in the bottom of the bearing table accommodating cavity, and the central axis of the second permanent magnet coincides with the central axis of the circular groove in the bot
