Title: Dynamique d'un rotor embarqué soumis à des excitations combinées de la base
Author: DAKEL, MZaki; BAGUET, Sébastien; DUFOUR, Régis
Abstract: The proposed on-board rotor model is based on Timoshenko beam finite elements. It takes into account the six translations and rotations of the rigid support and the geometric asymmetry of disks and/or shaft. Thus the obtained equations of motion contain time-varying parametric terms which can lead to lateral dynamic instability. The influence of combined rotational and translational support motions is analyzed by means of Campbell diagram and rotor stability chart.
