Abstract

La présente invention concerne un procédé de mesure d'un couple de torsion (Mt) utilisant l'effet magnétostrictif inverse. Le couple de torsion (Mt) agit sur un élément de machine (01) s'étendant sur un axe (02) et conçu pour transmettre le couple de torsion (Mt) à l'intérieur d'un agencement d'éléments de machine. L'élément de machine (01) est en outre soumis à une force transversale (FQ) qui agit dans une direction perpendiculaire au couple de torsion (Mt). Une valeur du couple de traction (Mt) et une valeur de la force transversale (FQ) sont proportionnelles. L'élément de machine (01) comporte au moins une zone magnétique (03) qui s'étend périphériquement autour de l'axe (02) pour produire une magnétisation. On utilise par ailleurs pour la mesure au moins un capteur (06) de champ magnétique qui est conçu pour mesurer individuellement un champ magnétique provoqué par la magnétisation et par le couple de torsion (Mt). Une étape du procédé consiste à déterminer une erreur de décalage du capteur (06) de champ magnétique. Une autre étape consiste à compenser l'erreur de décalage dans un signal de mesure du capteur (06) de champ magnétique.
