Novel semi-submersible wind wave energy coupling electric energy supply platform based on tuned damping

The invention relates to the technical field of wind wave energy coupling electric energy supply platforms, in particular to a novel semi-submersible wind wave energy coupling electric energy supply platform based on tuned damping, which comprises a water ballast tank, a central upright post, a mooring system and a truss structure, the bottom end of each main stand column is fixedly connected with a heaving plate, the solid heaving plates are fixed to the bottoms of the hollow main stand columns, each main stand column is internally provided with a main stand column inner cavity, and ballast water with the size smaller than that of the main stand column inner cavity is contained in the main stand column inner cavity. The semi-submersible electric energy supply platform is based on the tuning liquid damping principle, the effect of slowing down motion response can be achieved under the abnormal general situation that an original structure generates strong vibration or pitching and rolling motion, the self-stab
