Abstract
It is shown how weight reduction of cylindrical grid structures can be achieved by using axial-helical instead of helical-circumferential orientation of ribs. The optimization process mainly relies on an analytical model. A finite element model is used for validation and fine-tuning. Constraints are stability and material failure. Studies on the influence of rib heights and Young’s modulus reveal potential to create lighter grids in axial helical design. Also, the main mechanical differences of both grid types and their influence on structural weight are elaborated.
