1. A nacelle for a wind turbine, comprising:
a housing surrounding an interior space of the nacelle;
a nacelle support structure disposed within the interior space of the nacelle, wherein the nacelle support structure has a top side and a bottom side, and supports a drive unit of the wind turbine on the top side;
at least one tuned mass damper disposed within the interior space of the nacelle, attached to the bottom side of the nacelle support structure, wherein the at least one tuned mass damper is tuned to target at least one mode of motion of the nacelle in a frequency range below 50 Hz, wherein the at least one tuned mass damper is attached to a rear-end portion of the nacelle support structure, the rear-end portion of the nacelle support structure being disposed behind an attachment point to a tower of the wind turbine in a direction along the nacelle from a rotor of the wind turbine to a rear-end of the nacelle, and wherein the rear-end portion hangs freely above the ground and is not directly supported by the tower.
