民机的翼面结构作为飞机主要的承力部件,在飞机的使用过程中承受较大的载荷,结构气动变形较大。因此,飞机翼面结构主要按刚度设计,研究分析计算复合材料翼面沿弹性轴的各剖面的刚度特性和分布是翼面结构刚度设计的关键。本文提出一种复合材料翼面剖面刚度的工程计算方法,为类似结构刚度分析提供参考。
Civil aircraft’s airfoil structure as the aircraft’s main load-bearing components, the aircraft in the process of using to withstand greater load, the structure larger aerodynamic deformation. Therefore, the structure of the aircraft’s airfoil is mainly designed according to its stiffness. Studying and analyzing the stiffness characteristics and distribution of the composite airfoils along the elastic axis is the key to the design of the stiffness of the airfoil. In this paper, an engineering calculation method for the profile stiffness of composite airfoil is proposed, which provides a reference for similar structural stiffness analysis.
