Contribution à l'étude des formulations de calcul de la force magnétique en magnétostatique, approche numérique et validation expérimentale

Abstract : This thesis presents methods associated to calculation of forces generated on linear material by magneto static fields. It proposes also to compare their accuracy on material with low permeability. The demonstration of these methods are taken into account and assumptions are highlighted. To discriminate these formulations, equivalent currents, equivalent magnetic masses, Maxwell’s Tensor, energy principle, an experiment and all associated measurements are designed by field calculation. A specific material with low modulus of elasticity is also synthesized. Under a magnetic field, a volume of such test material must provide significant deformations. Each formulation are able to provide stress distribution on this test volume. For each distribution, the deformation of volume is calculated. Each deformation is compared to the deformation provided by the experiment. It appeared that energy method is the most accurate method.
