Abstract
This paper presents the active vibration control of carbon nanotube (CNT) reinforced functionally graded plates using piezoelectric actuator and sensor pairs bonded on the top and bottom surfaces of the host plate. Three types of CNT distributions are considered. In this study, Reddy's higher-order shear deformation theory (HSDT) is applied to evaluate the displacement fields of the host plate. The equation of motion of the whole structural system is formulated by Hamilton's principle. To derive a set of discrete ordinary differential equation, the assumed mode method is used. For the active vibration control, velocity feedback control method is used to design the controller. Responses of the plate subjects to free and forced vibration are determined. The differences of vibrations between the three types of CNT reinforced functionally graded plates are compared. Influence of volume fraction of the CNTs on the vibration amplitude is investigated. The active vibration control effects of the velocity feedback controller are presented and the trend of change in the control effect with placements of piezoelectric patches is also examined.
