Paper Abstract

Giant magnetostrictive material (GMM) is an attractive material for sensors because of its characteristics including high relative permeability and high magneto-mechanical coupling coefficient. Based on the Villari effect and crystal anisotropy theory of this material, the mathematical models which describe the relation between GMM rod permeability and its pressure, the relation between induction coil inductance and its relative permeability were established in this paper. The models were simulated and analyzed by using MATLAB software. The results show that there is a good linear relationship between the pressure exerted on the GMM rod and the inductance of induction coil, which lays a theoretical basis to design a three-dimensional force sensor with high precision, high stability and good output characteristics.
