摘要

机翼翼型由特定飞行条件设计获得,其在各工况下的气动效率皆优问题亟待解决。研究变形翼柔性后缘机构,使其在连续光滑变形前提下,最大程度满足气动最优所需变形范围。采用变密度法拓扑优化方法,以某翼型实际位移与目标位移之间的最小平方差为优化目标函数,通过遗传算法优化确定柔性后缘多点驱动载荷作用位置,建立柔性后缘综合优化模型并采用移动渐近法求解。最后应用Ansys软件仿真对优化设计结果进行检验,表明该变形翼柔性后缘能够实现要求的连续变形,验证了优化设计方法的有效性。

Abstract

The wing is designed by specific flight conditions,and its aerodynamic efficiency under various conditions needs to be optimized.This paper studies the trailing edge of the morphing wing to make it meet the aerodynamic optimal deformation range under the premise of continuous smooth deformation.By using the method of topology optimization with variable density method,the minimum square error between the actual displacement of the airfoil and the target displacement is taken as the optimization objective function,and the position of the trailing edge multi-point driving load is optimized by genetic algorithm to establish the compliant trailing edge comprehensive optimization model.Using the moving asymptotic method to solve.Finally,the result was simulated by ANSYS,the effectiveness of trailing edge deformation is discussed and verified.
