摘要：

针对在新型制造技术背景下的航空轻量化结构发展,提出了次级加筋结构3种可能的形式,并对金属次加筋结构的稳定性问题进行了数值计算与优化研究。基于多学科优化软件ModelCenter与有限元(FEM)软件ABAQUS建立了金属次加筋结构优化设计的软件框架,利用粒子群优化(PSO)算法对各形式下次加筋结构的参数配置进行优化。分析了各形式的优化结构在单轴压载作用下,次加筋板对传统加筋板临界屈曲载荷以及极限承载能力的增益效果。结果表明,引入次加筋结构使传统加筋板的稳定性能与极限承载能力提升明显,对于适应新制造技术的航空轻量化结构设计有一定参考价值。

Abstract:

To promote the development of light weight aeronautical structure under the booming new manufacturing technology, three promising layouts of sub-stiffened thin wall structures are proposed and the corresponding design optimization regarding the structure's buckling behavior are conducted based on numerical simulation. A design optimization framework of sub-stiffened structure is developed based on the multidisciplinary optimization platform ModelCenter and finite element method (FEM) software ABAQUS. The framework is applied for the optimal designs of the three panel layouts with particle swarm optimization (PSO) algorithm. Three optimal sub-stiffened panels are acquired while the performance gains of critical buckling load and ultimate strength under uniaxial loading after sub-stiffening is introduced to the benchmark panel structure are analyzed. The result indicates that the introduction of sub-stiffening to the traditional stiffened panel can significantly improve the panel's buckling load and ultimate strength under uniaxial loading, and thus deserves further attention for aerospace industry which endeavors to develop high performance light weight structures with new manufacture technology.

Key words: sub-stiffening, stiffened panel buckling, PSO algorithm, finite element analysis, ultimate strength
