基于仿生扩散生长驱动的加筋板壳抗屈曲拓扑设计
Buckling Topological Design of Reinforced Plate/Shell Based on Bionic Diffusion Growth-driven Method
摘要
Abstract
To overcome the limitations of insufficient design spaces in existing Bio-inspired reinforced-plate design(BRD)methods resulting from the modeling strategy of the ground structure method(GSM),a diffusion-based growth scheme inspired by the vein growth patterns of plants was proposed.The scheme simulated the formation processes of plant venation to identify efficient stiffener layouts that enhanced the buckling load-bearing capacity of the structure.An improved optimization modeling framework was ad-opted,using S9R5 Shell elements and B32/B31 beam elements to simulate the plate(leaf)and stiffeners(veins)respectively.A scheme of node pre-storage and reserve/updating employed to expand the flexibil-ity of stiffeners by increasing the updating-range of active nodes.Rectangular thin plates were investigated as representative examples,buckling analyses under various parameters,boundary conditions(SSSS and SFSF),and loading cases were conducted to validate the effectiveness of the proposed method.The nu-merical results demonstrate that the diffusion-based growth scheme yields more efficient and clearer stiff-ener layouts compared to existing growth strategies.关键词
