摘要

Recent research has shown that embedded piezoelectric shear actuators lead to less damage and debonding, minor dependence on position and length, and smaller stresses, when compared to surface-mounted extension actuators. It was also observed that the latter are more effective for controlling very flexible structures while, for stiffer structures, the former are a better option. These and other distinctive features of extension and shear actuators may be exploited to study their simultaneous use and to design a combined extension-shear actuated beam. Hence, this work presents the results of a numerical investigation of active vibration control using simultaneous extension and shear piezoelectric actuation for a clamped-clamped sandwich beam. The analysis is carried out using a laminate/sandwich beam finite element model combined to an optimal control with limited input. Results show that simultaneous use of extension and shear actuators is very promising since their actuation mechanisms are complementary. Hence, better performance through a wide frequency-range can be obtained through very localized actuators.
