A model consisting of n five-degree-of-freedom subsystems has been developed to characterize some of the mechanical response features of a bladed disk system, including four modes of each blade, n bending modes of the disk, blade-to-blade and blade-t

The application of a tuned viscoelastic vibration absorber to undamped cantilever and clamped-clamped beams is discussed analytically. The cantilever beam is excited by a harmonically varying force at the free end, at which point the absorber also is

The presentation will review problems of damping in turbomachinery blades and bladed disks. The blade‐disk and blade‐to‐blade interface effects represent an important source of damping controlling vibration and stress levels. These effects are
