摘　　要：以可变体飞行器蒙皮结构设计中的蜂窝芯结构为研究对象,基于Gibson公式及Euler梁理论,在满足机翼实现连续变体的气动特性前提下,建立柔性蜂窝芯结构的参数优化模型。借助遗传算法对特定蜂窝芯单元选型参数进行多目标优化设计,得到了不同蜂窝芯结构的选型参数对面内变形能力的影响规律。根据不同蜂窝芯结构的面内变形性能,进行蒙皮蜂窝芯结构的选型分析,为可变形蒙皮蜂窝芯结构的选型提供了一些参考。The object for study is the honeycomb core structure in the design of variable aircraft skin structure, based on the Gib- son formula and Euler-beam theory, on the foundation of meeting the aerodynamic characteristics of continuous variation of wing, a parameter optimization model of flexible honeycomb core structure was built. With genetic algorithms for specific honeycomb core cell selection parameters for multi-objective optimization design, the influence of different honeycomb core structure＇ s selection parameters to in-plane deformation capacity is obtained. According to different deformation properties of the inner surface of the honeycomb core structure, the skinned honeycomb core structure was analyzed, a reference for the selection of the deformable skinned honeycomb core structure was given.
