Finite element analysis on active vibration control using lead zirconate titanate–Pt–based functionally graded piezoelectric material

Abstract

The numerical simulations for active vibration control of the host structure using lead zirconate titanate–Pt-based functionally graded piezoelectric material are presented in this article. The material properties (both mechanical and electrical) of the lead zirconate titanate–Pt-based functionally graded piezoelectric material are graded in the thickness direction according to the volume fraction power law distribution. The finite element modeling using first-order shear deformation theory is implemented to predict static and dynamic responses of the vibrating structure. A constant negative velocity feedback controller is designed to provide closed-loop feedback control. Both static and dynamic controls of the host structure are numerically simulated to demonstrate the effectiveness of the proposed lead zirconate titanate–Pt-based functionally graded piezoelectric material. The numerical results show significant variation in sensing and actuating capability up to a certain volume fraction index ( n).
