Design of anisogrid composite lattice conical shell structures
Journal Title: Journal of Science and today’s world - Year 2013, Vol 2, Issue 2
Abstract
Lattice structures due to their low weight and high performance as structural elements have been widely used in different aerospace applications. In this paper, effective parameters on the design of anisogrid lattice conical shells are investigated. First, filament winding patterns regarding the desired axial strength is decided. Then, regarding geometrical relations, effective parameters in order to form the anisogrid cell are identified. Distance of circular ribs from each other has an important role in determining the conical lattice structure and eventually in deriving the stiffness matrix. Finally, considering the relations, finite element analysis model of the lattice conical structure has been performed by ABAQUS software and buckling analysis under axial loading is done. In deriving the strength results, the verifications of references of this paper and the classic theory have been used.
