The invention relates to a tuning rotational inertia damping vibration attenuation device. The tuning rotational inertia damping vibration attenuation device comprises a rotational inertia mass block, a torsion damper and a rotating restoring force providing mechanism. One end of the rotating restoring force providing mechanism and one end of the tension damper are fixedly connected to a structure, and the other end of the rotating restoring force providing mechanism and the other end of the tension damper are connected to the rotational inertia mass block. The rotational inertia mass block is parallel to the rotating surface of the structure, the rotating restoring force providing mechanism is perpendicularly connected with the rotational inertia mass block, and the torsion damper is perpendicularly connected with the rotational inertia mass block. By the adoption of the structure, because the rotational inertia mass block parallel to the rotating surface of the structure is arranged, when the structure moves in a rotating mode, rotating motion can be transmitted to the rotational inertia mass block through the rotating restoring force providing mechanism, and accordingly the torsion damper is driven, the energy of the rotating motion is absorbed by the torsion damper, and the tuning rotational inertia damping vibration attenuation device has a very good damping effect.
