利用薄壁结构力学剖面计算的理论,通过计算获得全复合材料机翼的扭转和弯曲刚度及刚心位置,并进一步研究了桁条的结构布局对机翼整体结构刚度的影响。结果表明:机翼的剖面刚度随桁条的尺寸和分布的变化而改变,桁条最佳间距为130~150mm。该内容的研究为复合材料飞机机翼结构设计和气动弹性分析提供了重要依据。

The present study aimed at obtaining retorting stiffness, bending stiffness and stiffness center position of full composite wing using thin wall structure mechanics theory. The influence of stringer layout on wing integer structure stiffness was furthermore investigated. It is found that wing section stiffness was influenced by stringer layout and dimension. The best spacing of stringer was within the range from 130 to 150 mm. The study of this paper provided important support for structural design and aeroelastic analysis on composite wing.
