项目摘要

The proposed research will investigate and contribute in the development and advancement of additive manufacturing (AM) design approaches and methodologies. The initial goal will be to exceed the capability of current algorithms and commercial software packages, later implementing them into industry applications. Three main tasks will be completed during the three-year project: (1) Infill structure optimization, (2) Print orientation optimization, and (3) Transient thermal analysis of metal AM and optimization. These tasks seek to address the major challenges associated with integrating additive manufacturing into aerospace components by developing advanced computational tools and customized numerical models based on fundamental theories. The proposed project aims to solve several challenges with using additive manufacturing such as inherent residual stresses, part distortion, and support structure issues. All three tasks involve the redesign of components or systems to solve a real-world industry challenge. Through the partnership between researchers at Queen's University (Kingston, Ontario) and industry experts at Bombardier's aerospace division (Toronto, Ontario), the project will focus on theoretical advancements and their practical application to optimization modules. The partnership will feature a three-year project with a post-doctoral fellow and three full-time graduate students.

拟议的研究将在增材制造（AM）设计方法和方法论的开发和发展中进行调查和贡献。最初的目标是超出当前算法和商业软件包的能力，然后将其实施到行业应用中。在为期三年的项目期间，将完成三个主要任务：（1）填充结构优化，（2）打印方向优化，以及（3）金属AM和优化的瞬时热分析。这些任务旨在通过开发基于基本理论的高级计算工具和定制的数值模型来解决与将添加剂制造整合到航空航天组件相关的主要挑战。拟议的项目旨在解决使用添加剂制造（例如固有的残留应力，部分失真和支持结构问题）方面面临的一些挑战。这三个任务均涉及组件或系统的重新设计，以解决现实世界中的行业挑战。通过皇后大学（金斯敦，安大略省金斯敦）的研究人员与庞巴迪航空航天部（安大略省多伦多）的行业专家之间的合作，该项目将集中于理论进步及其对优化模块的实际应用。该合作伙伴关系将与一名博士后研究员和三名全职研究生进行为期三年的项目。
