| A nonlinear model of a rotating structure comprising a cylinder hub and three clamped thin-walled composite box beams is studied in this paper. The piezoelectric material layers are embedded into the specimens laminate to suppress vibrations of the rotor near resonance states. The reduced mathematical model of the rotor takes into account nonlinear electro-mechanical properties of the active blades as well as hub dynamics considered as a rigid body. Based on former authors research the governing equations of motion are written and resonance curves are obtained considering two system configurations, namely a fully symmetric design with identical beams and a non-symmetric one. The accounted for detuning results from the variation of the reinforcing fibres orientation and change in blade stiffness. To suppress vibrations a control unit is introduced to the system. This is represented in the mathematical formulation as an additional governing equation with quadratic coupling to the rotor generalized variables. This approach corresponds to the nonlinear saturation control strategy. Effectiveness of the proposed control method for selected operational states and excitation conditions is presented. |
