英文摘要
La fabrication d'un train d'atterrissage nécessite des attentions particulières car celui-ci est le composant le plus sollicité mécaniquement d'un avion avec des tolérances géométriques très serrées. SAFRAN Landing Systems, un leader mondial dans les systèmes d'atterrissage, désire augmenter sa productivité afin d'être plus compétitif. Le processus de fabrication d'un train d'atterrissage, fait en acier à haute résistance, inclut des étapes d'usinage pour donner la géométrie et un traitement thermique pour offrir les propriétés mécaniques désirées. Cependant, le traitement thermique s'accompagne d'un changement de géométrie pouvant rendre la pièce non-conforme, ce qui enclenche un processus coûteux de concession qui peut pour parfois finir par un rejet du composant. Afin d'éviter cela, un modèle prédictif est nécessaire permettant de quantifier la déformation qui résulte du traitement thermique. L'amélioration par essais et erreurs est très couteuse et non viable. L'utilisation de la simulation numérique est un choix intéressant, par contre, le traitement thermique implique des interactions de différents domaines physiques : la thermique, la métallurgie et la mécanique, rendant le problème très complexe. Les modèles existants de simulation sont incapables de fournir la précision requise dû à sur-simplification mathématique des modèles physiques. De ce fait, le projet aura pour objectif d'approfondir les connaissances sur les interactions thermo-métallo-mécaniques pour éventuellement avoir un modèle prédictif plus robuste.
