Abstract The vibration amplitude model of a giant magnetostrictive transducer was established using an equivalent circuit of the transducer. The model parameters were identified through an impedance analysis. The accuracy of the vibration amplitude model was improved by analyzing the effects of the frequency and amplitude of the excitation voltage on the electromechanical conversion coefficient. The relation between the excitation frequency and the electromechanical conversion coefficient was obtained experimentally. Then, the electromechanical conversion coefficient was calculated for various frequencies using interpolation to relate the vibration amplitude to the excitation current. Comparison with experimental results shows that the vibration amplitude model determined by the impedance analysis can be used to predict the transducer vibration at resonance. The interpolated electromechanical conversion coefficients can be used to calculate the vibration amplitudes so that the theoretical relations between the amplitude and the current for different excitation frequencies are consistent with experimental results, which indicates that the model has the proper relationships between the electromechanical conversion coefficient and the excitation frequency.
