Abstract
The concept of intelligent structure or smart structure can be used for abatement or elimination of vibration of structures used in aerospace industry. Through active vibration control the performance of structures can be improved significantly. A three-dimensional finite element analysis of a cantilever plate with bonded piezoelectric actuators is carried out, with a view to seeking the optimal location of actuators on the plate. ANSYS software package, finite element program is used to carry out modal analysis and harmonic response analysis. The analysis points up the fact that active damping of structural vibration of the cantilever plate can be achieved by bonded piezoelectric actuators with optimal location.
