Vibration Control of Rotating Composite Thin-walled Beam Using Piezocomposite Actuators
نویسندگان
چکیده
Aim of this research is the vibration analysis and control of rotating composite thin-walled beam containing distributed piezoelectric sensors and actuators. The formulation is based on thin-walled, single cell composite beam including the warping function, centrifugal force, Coriolis acceleration and piezoelectric effect. Adaptive capability of thin-walled beam is obtained by PVDF sensor and piezocomposite actuator that are embedded between composite layers. A velocity feedback control algorithm coupling the direct and converse piezoelectric effect is used to actively control the dynamic response of an integrated structure through a closed control loop. Numerical study is performed using finite element method, and dynamic response of the thin-walled beam is investigated. Newmark time integration method is used to calculate the time response of the model. The effect of parameters such as rotating speed, composite lamination and fiber orientation of thinwalled beam are investigated in the numerical simulation.
