| 主权项 | 1. A planar component comprising a sheet metal element having a bead formed thereon, at least one piezoelectric actuator for active vibration damping, wherein the piezoelectric actuator is applied to an inside or an outside of a bead, wherein the bead has a place of maximum curvature and the piezoelectric actuator is applied to the bead at the place of maximum curvature of the bead, wherein the sheet element is provided with at least one bead per each basic oscillation mode for damping the basic oscillation modes, which brings about its mechanical stiffening in this mode. | ||
