摘要：

To realize the lightweight design of filling bodies while ensuring that the umbilical cable has sufficient stiffness and strength after the weight of filling bodies is reduced, the topology optimization design is accomplished for four filling bodies with typical cross-sectional shapes. Taking the traditional full filling space as the design variable and minimizing the compliance of the structure as the optimization objective, an optimization model was proposed under the condition of strength constraints. Meanwhile, numerical models of the cross-sections of umbilical cables with different filling forms were constructed. The cross-sectional mechanical properties of these models, such as radial deformation, the stress of the key components, and contact pressure among the components, were selected as evaluation indicators for lightweight design. The topology optimization results were verified by finite element analysis. The results show that for the umbilical cable selected in this case, the total mass of the optimized filling bodies was reduced by 14% under the premise of satisfying the mechanical properties of the umbilical cables. This study provides a useful reference for the structural engineering design of umbilical cables. Copyright ©2022 Journal of Harbin Engineering University.
