Abstract

This paper presents a magnetomechanical hysteresis model for a giant magnetostrictive device. In the model, the magnetization is characterized by the Jiles-Atherton model and the improved magnetomechanical effect model, the magnetic force is modeled by an equivalent magnetic circuit. In order to obtain optimal parameters of the model, a genetic algorithm is used. Comparisons between the experimental and calculated results show the validity of the model.
