Abstract

L'invention concerne le domaine de la mise en forme des panneaux métalliques de grande taille par grenaillage. L'invention consiste en un procédé incluant d'une part une gamme spéciale pour essais préalables de grenaillage sur éprouvettes du même matériau que celui du panneau à mettre en forme, lesdites éprouvettes étant grenaillées soit jusqu'à saturation soit durant un temps donné, et d'autre part un programme informatique, basé sur des règles prédéfinies au moyen de descripteurs intelligents sélectionnés et comportant une simulation numérique, et dans lequel sont introduites les caractéristiques du matériau et les données géométriques réelles du panneau à mettre en forme ainsi que les résultats des essais préalables sur éprouvettes de matériau identique au panneau. Le programme informatique permet de : 1/ calculer à l'aide d'un opérateur mathématique spécial qu'en chaque point les paramètres transformés structuraux du panneau vérifient le critère de plasticité, utilisant le fait que pour le grenaillage un champ de variation de déformation plastique périodique à valeur finale nulle est introduit, 2/ prendre en compte des zones sur le panneau, 3/ calculer une matrice dite matrice d'influence définissant l'incidence du grenaillage d'une zone particulière sur les autres zones en fonction des paramètres de grenaillage 4/ donner la forme finale qui serait obtenue pour le panneau avec des conditions et des paramètres déjà définis pour la machine à grenailler. 5/ donner automatiquement les conditions et les paramètres à utiliser sur la machine pour d'atteindre la forme finale requise imposée à partir d'une forme initiale réelle donnée.
