摘　　要：为了探讨双机身大展弦比直机翼无人机中基于翼面弯曲刚度下机身与机翼的最佳布置问题, 本文采用工程梁对这一问题进行建模, 并利用MATLAB6. 5的优化工具箱给出数值优化解。在此工作的基础上,研究了翼面扭转刚度, 计算结果表明, 与单机身布局相比, 双机身布局中的翼面结构扭转刚度提高了4倍。结合文献[1]的工作, 可以得出结论: 就结构刚度(弯曲和扭转)而言, 双机身布局具有一定的优势, 值得做进一步的分析。In order to study the optimal layout about fuselage and wing based on wing bending stiffness on bi-fuselage aircraft with high aspect ratio straight wing, the authors utilized the engineering beam to model this physical problem and gave the numerical solution through the optimization tool box of MATLAB 6.5. On the basis of the above work, the wing torque stiffness was also discussed. The computational result showed that the wing torque stiffness of bi-fuselage aircraft increased 4 times comparing with that of single-fuselage. Combined with the result of reference 1, we could draw a conclusion that the bi-fuselage layout had an advantage over single-fuselage layout and deserved to study in detail, with regard to structural stiffness (bending and torque).
