Presidential Faculty Fellows Award: Development of Methods for Multidisciplinary Design

小行星9553210 该补助金为总统学院研究员奖提供资金。 该奖项期间的研究将侧重于为复杂的多学科工程应用开发计算设计策略，旨在解决行业问题。 多学科设计（MD）问题的典型代表是学科之间的复杂耦合，需要新的设计策略，考虑到这些耦合。 该奖项的主要研究领域包括：“系统简化策略”，以减少分析模型的大小，而不牺牲系统的准确性;“最佳排序”，以确定参与学科子系统的最佳排序，以降低整体计算成本;“混合系统的分解”，以制定适用于连续和离散变量情况的分解策略;以及“解耦子系统的协调”，其中必须量化子系统之间的协调系数以用于分解策略。 教学目标将侧重于在本科课程中添加实验室组件，翻新现有的研究生课程，包括团队和计算组件，开发新的研究生课程，开发多学科设计工程硕士学位课程，并专注于研究生培训和指导。 所提出的方法的成功开发可以导致用于复杂系统的设计的显著改进的过程，诸如在飞机、汽车、海军船只、高速列车、甚至发电厂中发现的。 在传统的串行设计环境中，对于设计周期的每个阶段，进行更改的成本都会增加一个数量级。 由于最近竞争激烈的市场压力，它已成为明显的，对于复杂系统的设计，所有的要求，制造和生命周期的问题，必须解决整个设计过程的所有阶段。 这导致知识曲线发生移动，从而在设计自由度仍然很高的情况下获得更多有关设计的知识。 产品日益复杂，需要新的方法和流程来提供下一级的集成。 多学科设计（MD）是国家公认的关键技术。 只有在过去的几年里，航空航天以外的行业才认识到MD是一门可以满足他们许多需求的学科。 MD有可能获得开发时间和成本的大幅减少，以及提高性能。

9553210 Bloebaum This grant provides funding for a Presidential Faculty Fellow Award. Research during the period of the award will focus on developing computational design strategies for complex, multidisciplinary engineering applications, aimed at addressing industry problems. Multidisciplinary Design (MD) problems are typified by complex couplings between disciplines which necessitate new design strategies that take these couplings into account. The major areas of research during the term of this award include: 'System Reduction Strategies' to reduce the size of the analytical models without sacrificing system accuracy; 'Optimal Sequencing' to determine the best ordering of the participating disciplinary subsystems to reduce overall computational cost; 'Decomposition for Mixed Systems' to develop decomposition strategies for application in situations where variables are of continuous as well as discrete type; and 'Coordination of Decoupled Subsystems' wherein coordination coefficients amongst subsystems must be quantified for use in decomposition strategies. Teaching objectives will focus on adding lab components to undergraduate courses, renovating existing graduate courses to include teaming and computational components, developing a new graduate course, developing a graduate Master of Engineering program in Multidisciplinary Design, and focusing on graduate training and mentoring. The successful development of the proposed methodologies could result in substantially improved processes for the design of complex systems, such as are found in aircraft, automobiles, naval vessels, high speed trains, and even power plants. In the traditional serial design environment, the cost of making a change increases by an order of magnitude for each phase of the design cycle. Due to recent competitive market pressures, it has become evident that for the design of complex systems, all requirements, manufacturing, and life-cycle issues must be addressed throughout all phases of the design process . This results in a shift of the knowledge curve, thereby yielding more knowledge about the design while the design freedom is still high. The increasing complexity of products requires new methods and processes to provide for this next level of integration. Multidisciplinary Design (MD) is recognized nationally as a critical technology. Only within the last couple of years have industries other than aerospace recognized MD as a discipline that can address many of their needs. MD has the potential to obtain substantial reductions in both development time and costs, as well as improved performance.
