Abstract
Hybrid vibration control of laminated composite beams has been carried out using piezoceramic sensor/actuator and viscoelastic material. Collocated piezoceramic sensor/actuator is mainly used to control the first bending mode and the viscoelastic material is used to control the second bending mode by passive constrained-layer damping. The passive constrained-layer damping has been analyzed by formulating the equations of motion through the use of extended Hamiltoní»s principle. The dynamic characteristics such as damping ratio and modal damping of the beams are calculated for various fiber orientations by means of iterative complex eigensolution method based on finite element method. Active control of vibration of the cantilevered laminated composite beams using collocated piezoceramic sensor/actuator is analyzed theoretically and verified experimentally for various fiber orientations. Impact on the stiffness and damping properties by varying stacking sequence is studied. This paper addresses a design strategy of laminated composite under vibrations to design a structure with maximum possible damping capacity.
