摘　　要：为了研究歼击机水平尾翼大轴的结构设计,本文采用工程梁理论进行结构建模,将尺寸变量与坐标变量作为两个设计空间中的设计变量,其中,利用近似函数与黄金分割法相结合进行尺寸优化,再使用Nelder-M ead单纯形方法进行几何优化,分别进行交替优化,直至迭代收敛。实际算例的优化结果表明,与传统的经验设计相比,本方法对大轴结构减重效果明显,在工程上是可行的。In order to deal with the structural synthesis design of fighter stabilizer torque tubes, a torque tube structure modeling is performed using the engineering beam theory with dimension and coordinate used as two design space variables. The approximate function is combined with the golden section method for dimension optimization. Then, the Nelder-Mead simplex method is used for geometry optimization. Finally, this problem is alternately optimized in the two spaces until the iterations are converged. The optimization results of an engineering example show that the proposed vides relatively significant effects of weight saving of torque tubes over traditional design approach proapproaches.
