Abstract:

In this paper, the authors propose a model for dynamic magnetostrictive hysteresis in a thin rod actuator. They derive two equations that represent magnetic and mechanical dynamic equilibrium. The model results from an application of the energy balance principle. It is a dynamic model as it accounts for inertial effects and mechanical dissipation as the actuator deforms, and also eddy-current losses in the ferromagnetic material. The authors show that the model admits a periodic solution that is asymptotically stable when a periodic forcing function is applied.
