Active vibration control of piezo-laminated cantilever beam

Das, Sidharth and Baral, Joy and Chatterjee, Peenak (2011) Active vibration control of piezo-laminated cantilever beam. BTech thesis.



In active vibration control the vibration of a structure is reduced by using opposite directional force to the structure. Now a day‟s active vibration control is frequently being used in aircraft, submarine, automobile, helicopter blade, naval vessel. In this project a smart plate (aluminum plate) with one pair of piezoelectric lamination is used to study the active vibration control. The smart plate consists of rectangular aluminum beam modeled in cantilever configuration with surface bonded piezoelectric patches. The study uses ANSYS-12 software to derive the finite element model of the smart plate. Based on this model, the optimal sensor locations are found and actual smart beam is produced. In this experiment we find a suitable control methodology by which we optimize the controller gain to get more effective vibration control with minimum control input.
