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.
