Multi-disciplinary topology optimization for metal additive manufacturing under uncertainty

由于社会日益全球化以及许多新兴国家的持续发展，全球航空客运量每年都在大幅增长，这些国家的航空客运量增长幅度最大。为了保持商业航空旅行的环境可持续性，需要采用许多新技术，以充分提高每架飞机的效率，从而使效率的提高可以抵消计划中的需求增长。由于飞机重量和燃料需求之间的递归关系，减轻重量有望成为实现这些关键效率提高的最直接方法之一。**提出的工作概述了有助于下一代商用飞机减轻重量的三个主要研究任务：多学科拓扑优化，金属部件增材制造的分析和优化，以及增材制造相关不确定性下的设计。这三项任务都是建立在现有技术的基础上，但在它们能够有效地应用于航空航天工业的问题之前，需要进行大量改进。本研究的主要目标是开发先进的多物理场建模和设计优化方法，以消除这三个领域的进入障碍。**通过皇后大学的研究人员与加拿大普惠公司领先的行业专家和设施之间的合作，该项目将重点关注特别适用于航空航天工业的理论进步。* * * * * *

Global air passenger volumes continue to rise substantially each year, driven by increasing globalization of society and the continued development of many emerging countries who are showing the largest increases in air traffic. To keep commercial air travel environmentally sustainable, many new technologies need to be incorporated in order to adequately improve the efficiency of each aircraft, so that improvements in efficiency can offset the planned increases in demand. Due to the recursive relationship between aircraft weight and fuel requirements, weight reduction promises to be amongst the most straightforward methods of achieving these critical efficiency improvements.**The proposed work outlines three primary research tasks, which will help to reduce weight in the next generation of commercial aircraft: multi-disciplinary topology optimization, analysis and optimization for additive manufacturing of metal components, and design under the uncertainties associated with additive manufacturing. All three tasks seek to build upon existing technologies, but require substantial improvement before they can be applied effectively to problems in the aerospace industry. The primary objective of this research is develop advanced multi-physics modeling and design optimization methodologies to remove the barrier to entry in each of these three fields. **Through partnership between researchers at Queen's University and leading industry experts and facilities at Pratt & Whitney Canada, the project will focus heavily on theoretical advancements that are highly applicable to the aerospace industry in particular. ******
