چکیده

This paper presents a framework for the calculation of functional requirements at several stages of the product life cycle. It uses the TTRS/MGRE concept for the determination of dimension chains. The geometry of the assembly is represented using a parametric model constituted of points and vectors. Finally, it also integrates the calculation of part deformation due to changing operating conditions thanks to existing techniques such as finite elements. RÉSUMÉ. Ce papier présente le cadre de développement d’une méthode pour le calcul d’une exigence fonctionnelle donnée à plusieurs étapes du cycle de vie du produit. Cette méthode utilise les concepts de SATT et EGRM pour déterminer les chaines de cotes. La géométrie est représentée grâce à un modèle paramétrique constitué de points et de vecteurs. Enfin, le calcul des déformations mécaniques dues au changement des conditions d’utilisation sera intégré par l’utilisation de techniques existantes comme les éléments finis.
