Variable-Complexity Design Strategies for Integrated Multidisciplinary Optimization

这项工作是复杂工程系统跨学科设计的一种综合方法。传统的设计过程包括使用简单、基于经验的方法的概念设计阶段，以及涉及中间模型的初步设计阶段，最后是具有复杂数值模型的详细设计阶段。各种工程学科的整合几乎完全在概念设计中进行。这项研究开发了一种综合这些设计阶段的方法，以实现更好的设计集成。该方法将基于经验的方法与基于计算的方法相结合，将简单模型与复杂模型相结合，将全局逼近与局部逼近相结合。除了实现更好、更高效的集成设计外，我们的目标是培养具有设计洞察力的数值型分析师。本研究是在飞机机翼气动-结构-控制同时设计的框架下进行的。

This work is a synthesized approach to the interdisciplinary design of complex engineering systems. The traditional design process involves a conceptual design stage which utilizes simple, experience-based methods, along with a preliminary design stage involving intermediate models and finally a detailed design stage, with complex numerical models. The integration of the various engineering disciplines takes place almost entirely within the conceptual design. This research develops a way of synthesizing these design phases in order to achieve better design integration. The approach combines experienced-based methods with computationally-based methods, combines simple models with complex models, and combines global approximations with local approximations. The objective, besides achieving better and more efficient integrated designs, is the education of numerically- oriented analysts with design insight. The research is conducted in the framework of the simultaneous aerodynamics-structures- control design of aircraft wings.
