Abstract
Résumé

A three-dimensional finite element model for the numerical simulation of metal displacement and heat transfer in the squeeze casting process has been developed. In the model, a numerical approach, termed as ‘Quasi-static Eulerian’, is proposed, in which the dynamic metal displacement process is divided into a certain number of sub-cycles. In each of the sub-cycles, the dieset configuration is assumed to be static and a fixed finite element mesh is created, thus making the Eulerian approach applicable to the solution of metal flow and heat transfer. Mesh-to-mesh data mapping is carried out for any two adjacent sub-cycles to ensure that the physical continuity of the real metal displacement process is represented. A numerical example is presented, which shows the application of the present model to geometrically complex three-dimensional squeeze casting problems.

Un modèle tridimensionnel basé sur l'approche éléments-finis à été développé pour la simulation numérique du déplacement du métal et des transferts thermiques lors du processus de moulage–forgeage. Dans le modèle, l'approche numérique, dénommée « Quasi-static Eulerian » est proposée, où le déplacement de métal est divisé en un certain nombre de sous-cycles. Dans chaque sous-cycle, la configuration est supposée être statique et un maillage élément-finis fixe est généré, ceci permettant l'utilisation de l'approche Eulérienne à la solution du métal en écoulement et aux transferts de chaleur. Le traitement d'information de grille à grille est possible entre les deux sous-cycles adjacents et permet d'assurer et de représenter la continuité physique du processus de déplacement réel du métal. Un exemple numérique est présenté, et montre l'application du présent modèle à des géométries complexes tridimensionnelles de problème de moulage forgeage.
