Abstract

In this paper, the modeling of force sensors built with rare-earth iron giant magnetostrictive materials is studied. For such a purpose, a magneto-mechanical strongly coupled FE model is proposed. Using the proposed model, the input-output characteristic of a force sensor built with giant magnetostrictive material (Tb-Dy-Fe alloy) is calculated. The obtained results are compared with the measured ones to examine the validity of the proposed magneto-mechanical strongly coupled model and the FE implementation. Satisfactory agreements are achieved. This indicates that the proposed FE model can be used in the design and optimization of giant magnetostrictive force sensors
