Abstract
In this paper the mechanical behavior of satellite carrier adapter made of composite lattice shell is examined. First, the geometrical parameters of the composite lattice shell are analyzed. Choosing the direction for winding the fibers (geodesic route), geometric equations of the structure is elicited. Then, stiffness matrix of the structure is obtained according to these equations. Finally using finite element modeling of a conical lattice shell sample, the comparison between finite element and analytical results are presented. The analytical and numerical results show that with increasing rib’s thickness and Width, axial strain of the structure decreases nonlinearly.
