NUMERICAL ANALYSIS OF A 2D VECTOR HYSTERESIS MEASUREMENT SYSTEM UNDER CONSTRUCTION

Miklós Kuczmann

   This paper deals with the numerical analysis of a vector hysteresis measurement system which is under construction. The aim is to build up a single sheet tester with round shaped specimen. The goal of simulations is to find out the main features of the measurement system. The 3D finite element method (FEM) with tetrahedral mesh has been applied for investigations of the nonlinear eddy current field problem. The characteristic of the magnetic material has been taken into account by the isotropic vector Preisach model. The nonlinearity has been handled by the polarization method and the nonlinear system of equations has been solved by the fixed point technique. The first results are presented in this work.

Keywords: vector hysteresis measurement, vector hysteresis model, finite element method, fixed point technique
