Abstract
An apparatus includes a hub, a first disk, a second disk, and a spacer. The hub is supported for relative rotation about a stationary component. The first disk is mounted to the hub with a first dynamic resonance mode associated therewith. The second disk is mounted to the hub with a second dynamic resonance mode associated therewith. The spacer is positioned between the first disk and the second disk, wherein the spacer is operable to cause the first dynamic resonance mode to be different from the second dynamic resonance mode.
