The dynamic behavior of elastic circular disks mounted on a flexible rotor has been investigated by a three-dimensional finite element model (distributed masses). The results are discussed and compared with an equivalent system assuming rigid disks (concentrated mass) for the nonrotating case. Interactions between the disks and disk and shaft during resonances have been demonstrated. Natural modes of a disk component and of the entire structure, supported by flexible bearings, are shown by computer plots in orthographic projections.
