| Abstract: | This paper gives the structural dynamic FEM model and corresponding FEM software package for a certain honeycomb sandwich composite satellite fairing. The natural frequencies and modes of the whole and half fairing under different boundary conditions are calculated. The separation behavior of half fairing and the load distribution in all binder blots subjected to aerodynamic load are analyzed. |
