In this work, a functionally graded spherical piezoelectric transducer (FG-sPET) with an accurate theoretical model is proposed, which facilitates the evaluation of the whole mechanical vibration system. The effects of geometric dimensions and non-uniform coefficients on vibration characteristics were studied to guide the structural optimization design of functionally graded piezoelectric devices.
In this work, a functionally graded spherical piezoelectric transducer (FG-sPET) is proposed and an accurate theoretical model is constructed, mainly composed of a three-port electromechanical equivalent circuit model (EECM). The EECM of FG-sPET can be connected to that of other vibration systems according to the boundary conditions (force and vibration velocity), making it easier to evaluate the whole mechanical vibration system. The validity of the EECM for FG-sPET is verified by comparison with other literature. The effects of geometric dimensions and non-uniform coefficients on the vibration characteristics (resonance/anti-resonance frequencies and effective electromechanical coupling coefficient) of FG-sPET are also studied, contributing to systematically evaluating the key factors determining the vibration characteristics of FG-sPET. The proposed analytical system is of excellent guidance for the structural optimization design of functionally graded piezoelectric devices. (c) 2022 Acoustical Society of America.
