Active Vibration Control of Functionally Graded Carbon Nanotube Reinforced Composite Plate with Coupled Electromechanical Actuation

Piezoelectric materials possess excellent electromechanical coupling characteristics, which are functional and suitable in structural vibration control. This study investigates the active control of free forced for piezoelectric-integrated functionally graded carbon nanotube reinforced composite (FG-CNTRC) plate using finite element method (FEM). Based on first-order shear deformation theory (FSDT), governing equations motion a FG-CNTRC derived by Hamilton’s principle. The convergence accuracy numerical is verified through results natural frequencies. influences CNT volume fraction, distribution type, piezoelectric layer thickness-to-plate thickness ratio, boundary condition frequencies investigated. A constant gain velocity feedback algorithm used to achieve dynamic response plate. In addition, effects load, gain, studied. Numerical indicate that promising practical applications civil mechanical engineering.
