摘要: 为提高总体设计的质量和效率,研究了民用飞机机翼结构及整体油箱的设计措施,并在一个开放式飞机总体设计环境中实现这一功能.定义了飞机翼面坐标系,提出了机翼、梁/墙、桁条、翼肋和蒙皮的参数化描述及模型构建方法,建立了交互式机翼结构及油箱三维设计环境,自动获取结构及油箱的体积、重量、重心和惯性矩等物理信息.在此基础上,实现了机翼结构和整体油箱的自动化模型调整及几何体质量特性的自动重算,为总体设计阶段进行飞机重量、气动和结构的多学科设计优化奠定了基础.最后,给出设计实例说明了机翼结构的设计和自动化调整方法是有效的.Abstract: In order to improve the quality and efficiency of civil aircraft conceptual/preliminary design, the implementation of wing structure and associated fuel tank design in a computer aided aircraft conceptual/preliminary design system were studied. The coordinate of wing-like components was defined. The parametric modes of wing, spar, stringer, rib and skin were represented. A prototype system for wing structure and associated fuel tank design were constructed, the characteristics such as weight, center of gravity, inertia were estimated too. The automatic adjustment and estimation of geometrical properties for wing structure and fuel tank were implemented, which were the base of multidisciplinary design optimization that took into account weight, aerodynamic and structure. At last, an instance was given to illustrate that the methods of wing structure design and automated adjustment are effective.
