dc.description.abstractThe present study deals with the identification and evaluation of some dynamic features of a laboratory designed and manufactured rotor. The rotor, embedded-free type, rotates in a vertical position. In the free side of the rotor, a disk with defaults is fixed to simulate some physical and aerodynamic phenomena. A dynamic unbalance which simulates a known specific critical regime is imposed to the structure. This type of aeroelastic dynamic instability, called gyroscope wavering, is characterized by a precession movement of the rotor which develops fatigue and increases loads on the structure. Identification and estimation of features inherent to the vibratory behaviour of the rotor, in this regime, are determined by two approaches: Finite elements and Rayleigh-Ritz methodsen_US
