Dynamic Strain Model With Eddy Current Effects for Giant Magnetostrictive Transducer
Based on the Jiles-Atherton model and transducer's structural dynamics principle, the magnetoelastic dynamic strain model of giant magnetostrictive transducer is founded. This model accounts for the eddy current losses and the variety of stress. Simulation results are in good agreement with the experimental ones. This indicates that the dynamic strain model can describe the relation between the applied field and the output vibration at different driving levels
