Abstract
In this article we present a theory describing the influence of the magnetostrictive component size on magnetically tuned electromechanical resonance frequencies (EMRs) for ferromagnetic–piezoelectric heterostructures. An analytical model to evaluate the magnetically tuned EMRs offset in strip–ring magnetoelectric composite structures is introduced. The model is applied to the specific case of PZT (ferrite-lead zirconate titanate)-strip/TDF (Terfenol-D)-ring composite. Numerical simulation of magnetically tuned EMRs offset indicated that the magnetically tuned EMRs depend significantly on the ratio of outer and inner radii of the magnetostrictive ring. A maximum value for the magnetically tuned EMRs offset Δf of −2.139×105Hz is found in a magnetic field H=8.641×10−2T for b=1.2a (b and a are outer and inner radius of magnetostrictive ring). This theoretical work is significant for designing ME devices and understanding the magnetically tuned EMRs in strip–ring composite structures.
