Analyse modale et étude des fréquences propres des réservoirs de carburant pour moteur-fusée

Abstract

In this study, two types of rocket fuel tanks were analyzed: a cylindrical tank, a spherical tank and a wing profile containing an integrated tank. Modal analysis was performed using ANSYS and COMSOL to evaluate the impact of various parameters (shape, material, thickness, etc.) on the natural frequencies. The results showed that some factors have a significant influence on the frequencies, while others have a limited effect. A good agreement was observed between the results from both software tools.
