Abstract
In this article, lead-free piezoelectric ceramics are investigated for active vibration control of piezolaminated composite shell structure. The shell structure is in the form of layered composite shell. Finite element modeling is performed to obtain vibratory response of the piezolaminated shell structure. Modeling is based on first-order shear deformation theory and linear piezoelectric theory. Fuzzy logic controller is used as controlling technique to reduce the vibration amplitude of vibrating shell using piezoelectric ceramics (both lead-based and lead-free). The simulation results reveal that Pb0.83La0.17(Zr0.3Ti0.7)0.9575O3 (lead zirconate titanate sensor) and (K0.475Na0.475Li0.05)(Nb0.92Ta0.05Sb0.03)O3 (KNLNTS actuator) combination reduces the vibration amplitude of vibrating shell structure faster than lead zirconate titanate (sensor) and lead zirconate titanate (actuator) combination. Moreover, for complete replacement of lead-based piezoelectric ceramics, 0.885(Bi0.5Na0.5)TiO3–0.05(Bi0.5K0.5)TiO3–0.015(Bi0.5Li0.5)TiO3–0.05BaTiO3 (BNKLBT sensor) and KNLNTS (actuator) combination is a potential candidate for active vibration control application.
