Abstract

Cet article prsente une application de la recherche de forme aux gilets de sauvetage gonflables. La recherche de forme est le nom gnrique dsignant le processus de conception de la forme globale des structures lgres instables telles que les structures gonflables. L’tat d’quilibre statique des gilets gonflables est recherch pour analyser leur forme, le volume contenu et la localisation des zones de plis. La mthode de relaxation dynamique avec amortissement cintique permet d’viter le problme de singularit de la matrice de raideur et le problme d’instabilit locale dans les zones de plis. Sa rapidit de convergence est trs dpendante de la formulation de la matrice des masses. Dans cet article, plusieurs expressions des masses sont testes et leurs performances compares entre elles sur un cas de gilet de sauvetage gonflable.
