Paper Abstract

We have developed a numerical simulation scheme for magnetostrictive transducers, which is based on the magnetic vector potential formulation. Therewith, magneto-dynamic problems including eddy currents can be treated and the restriction to magnetostatic problems is eliminated. Furthermore, the full coupling of magnetic and mechanical systems including magnetically induced mechanical strains and permeability changes due to mechanical stresses is taken into account. As an application, we will present numerical simulations for a magnetostrictive rod actuator and compare these results with measured data.
