摘　　要：为了研究铺层区域变量对大展弦比机翼静气动弹性的影响,本文在考虑几何非线性影响下,依据有限元分析,研究了外翼段铺层区域的划分以及90°铺层角度的个数对大展弦比机翼静气动弹性特性的影响。结果表明,0°、±45°、90°混合铺层的铺设效果优于只有0°、±45°铺层的区域;机翼变形情况随着外翼段铺层区域的增大而减小,且减小斜率逐步增大;外翼段铺层区域固定时,增加90°铺层角度个数会有效减小机翼变形,且机翼变形情况与增加的个数基本呈现负相关关系,其个数在铺层设计中可能存在一个最佳取值或最优占比。In order to investigate the influence of lay-up area variables on the static aeroelasticity of a high span ratio wing,this paper uses finite element analysis to investigate the influence of the division of the outer wing section lay-up area and the number of 90°lay-up angles on the static aeroelasticity of a high span ratio wing,while accounting for geometrical non-linearity.The results show that the effect of 0°,±45°,and 90°mixed lay-ups is superior to that of 0°and±45°lay-ups alone;the wing deformation decreases with the increase of the outer section lay-up area,and the slope of the decrease gradually increases;when the outer section lay-up area is fixed,increasing the number of 90°lay-up angles effectively reduces the wing deformation,and the wing deformation essentially shows a negative correlation with the number of plies,there may exist an optimal value or optimal ratio in the ply design.
