Integrated Structural-Aerodynmaic Design Optimization

为提高性能和降低制造成本而量身定做的材料适用于从汽车到土木工程结构再到喷气发动机的各种产品。然而，有效利用定制材料需要几个学科的设计集成。这一设计过程的整合是本研究的主题。建议的研究集中于将气动和结构设计的过程作为设计集成的原型。将探索两种方法：同时分析和优化，寻求优化结构和空气动力学的组合方程；第二，部分解耦，分别优化每个部分，并通过有限数量的交叉敏感导数将它们组合在一起。期望这项研究将为多学科设计优化带来更好、更有效的技术。虽然这里考虑的是飞机结构-气动优化，但数学和计算机技术在未来的跨学科设计中有着更广泛的应用和重要意义。主要研究人员在优化技术和结构力学领域享有良好的声誉。

The tailoring of materials to improve performance and reduce manufacturing cost is applicable to a wide range of products from cars to civil engineering structures to jet engines. However, the efficient utilization of tailored materials requires the design integration of several disciplines. This integration of the design process is addressed by this research. The proposed research is focussed on integrating the processes of aerodynamic and structural designs as a prototype for design integration. Two methods will be explored; simultaneous analysis and optimization, which seeks to optimize the combined equations for structures and for aerodynamics, and second, partial-decoupling, which optimizes each part separately and fits them together through a modally reduced number of cross-sensitivity derivatives. It is expected that the research will lead to improved and more efficient techniques for multi-disciplinary design optimization. Although aircraft structural-aerodynamic optimization is considered here, the mathematical and computer techniques have a wider application and importance to future inter-disciplinary designs. The principal investigators have a good reputation in the area of optimization techniques and structural mechanics.
