Abstract
This article deals with selection and performance evaluation of various piezoelectric materials for active vibration control (AVC) application. Finite element method is used to assess the relative importance of materials properties (Young's Modulus (E), piezoelectric constants (e31), dielectric constant (ε), density (ρ) and Poisson's ratio (υ)) for sensor and actuator applications which are eventually used in active vibration control. Analytical hierarchy process (AHP) is finally used to assign weights to all the properties understudy. Rankings made by multiple attribute decision matrix (MADM) approach show good agreement with finite element (FE) simulation results. The numerical simulations reveals the superior performance of K0.5Na0.5NbO3-LiSbO3-CaTiO3(KNN-LS-CT (1 wt. %)) as sensor followed by KNN-LS-CT (2 wt. %) and K0.475Na0.475Li0.05 (Nb0.92Ta0.05Sb0.03) O3 (KNLNTS). For actuator, Pb [ZrxTi1-x] O3 (PZT1) demonstrates the superior performance followed by KNLNTS and KNN-LS-CT (1 wt. %). The lead-free piezoelectric materials are potential candidate to replace lead-based piezoelectric materials for active vibration control application.
