摘　　要：建立自转旋翼机龙骨的有限元模型,对自转旋翼机龙骨进行静力分析。以自转旋翼机龙骨的各个结构管的截面尺寸作为设计变量,以自转旋翼机的总质量为设计目标,运用ANSYS优化模块对自转旋翼机的轻量化设计进行初步研究。基于优化设计软件iSIGHT,通过试验设计和有限元分析结构建立龙骨设计变量与优化目标的径向基函数神经网络模型。利用NSGA-Ⅱ优化算法进行求解,完成对自转旋翼机龙骨的优化。The static analysis of the keel of a gyroplane is carried out by establishing the finite element model of the keel.The cross-sectional dimensions of each structural tube of keel are taken as design variables,taking the total mass of the gyroplane as the design objective,using ANSYS optimization module to preliminarily study the lightweight design of the gyroplane.based on the experimental design and finite element analysis,a Radial Basis Function(RBF)neural network model of keel is made.Using the NSGA-Ⅱoptimization algorithm to solve the problem and complete the optimization of the keel.
