【摘要】 以COMPASS为平台研究了蒙皮铺层主方向角对机翼气动弹性的影响,以及采用不同形式的多项式函数表示蒙皮厚度的方法,分析了设计变量的敏度计算方法,并运用优化的方法对两个复材机翼结构进行了位移、频率、发散和颤振速度约束下的剪裁设计,获得了结构响应与主方向角的变化曲线和机翼表面的厚度分布等高线。研究结果表明本方法拓宽了复材机翼的设计手段,具有广阔的应用前景。更多还原

【Abstract】 In this paper,based on COMPASS,the influence of fiber orientation to wing aero-elastic performances and thickness representations by different types of polynomial functions is studied,and sensitivity of design variables is analyzed.Two wings are tailored under requirements of displacement,frequency,divergence and flutter by means of optimization,and the behavior curves and contours of thickness are obtained.It is concluded that this method extends design technique of composite wing structure and has an application foreground.更多还原
