This research work was carried out to apply the homogenized modeling technique and to investigate the behavior of a prototype aluminium honey comb satellite structure under various kinds of mechanical loadings. It describes the static and dynamic analyses of prototype satellite structure that were carried out in Ansys Workbench V12.0. The structure is composed of aluminium honeycomb sandwich panels, fastened to each other by means of end attachments. It takes into account, the modeling approach, employed for modeling the honeycomb panels and to define contacts between the end attachments and walls of the panels. The structure is of cubical configuration. The structure’s FE model consists of panels, end attachments and other masses such as masses of subsystem housings mounted on the structure, modelled as non-structural masses so that the overall mass of the system and its centre of mass are identical to the actual physical structure. The boundary conditions for each of the analyses were finalized, based on the Launch Vehicle specifications. The curves of acceleration (g) v/s frequency for harmonic analysis and PSD acceleration for random vibration analysis were then obtained and the results of stresses and the displacements arising in the structure are discussed.
