摘要
本文研究了翼盒结构的可靠性分析及基于系统可靠性的结构优化设计方法。采用发展了的优化准则法枚举系统的主要失效模式,和Feng的高精度法计算系统破坏概率,提出两个迭代公式进行元件尺寸的优化设计。算例结果表明本文方法是中、大型结构系统可靠性分析及优化设计的有效方法。
The methods of system reliability analysis and optimization for wing-box structures are studied in this paper. The optimility criterion method is adopted to enumerate the significant failure modes and Feng's method with high accuracy is used for computing system failure probability. Two iterative formulae are presented to minimize the structural weight. The illustrative examples show that these methods are very efficient, especially for medium and large scale structures.
