This project focuses on design and fabrication for a novel class of mechanical system known as compliant mechanisms. Compliant devices replace elements traditionally assembled using joints and springs with compliant flexible members that use elastic deformations to transmit motions and forces. This allows the research to concentrate more on representation, translation, and interface issues of design and fabrication, and less on issues such as assemble and manufacturability. The domain of compliant mechanisms allows design and optimization to be performed on devices at both the macro and micro level (e.g., SFF and MEMS-type fabrication processes, respectively), and so will afford a unique opportunity to study the clean separation of design and fabrication analogous to the VLSI paradigm. This research targets three primary areas of compliant mechanism design and fabrication. Fundamental to this study is the optimal synthesis of compliant devices, both macro and micro. This includes the design and analysis of 3-D structures and the nonlinearities associated with large deformations. The ability to form more complex objects based on a library of standardized parametric components will also be explored. As the processes are generally not the same, the issue of designing and refining translation tools to move between representations is a critical component in this research. The choice of intermediate representations will be critically examined, and the appropriate translation tools will be developed. The goal here will be to push towards intermediate formats that are suitable to multiple fabrication processes, at both the micro and macro scales. Finally, the ability to test and refine designs for micro structures by the use of macro prototypes fabricated from the same initial model will be developed, and its utility in the design of MEMS devices will be carefully examined.

该项目专注于设计和制造一类新型机械系统，称为顺应机构。 顺应性设备取代了传统上使用接头和弹簧组装的元件，采用顺应性柔性构件，利用弹性变形来传递运动和力。 这使得研究能够更多地集中在设计和制造的表示、转换和接口问题上，而不是诸如组装和可制造性等问题上。 兼容机制领域允许在宏观和微观层面（例如，分别是 SFF 和 MEMS 型制造工艺）对器件进行设计和优化，因此将提供独特的机会来研究类似于 VLSI 范式的设计和制造的干净分离。 这项研究针对柔顺机构设计和制造的三个主要领域。 这项研究的基础是宏观和微观合规设备的优化合成。 这包括 3D 结构的设计和分析以及与大变形相关的非线性。 还将探索基于标准化参数组件库形成更复杂对象的能力。 由于过程通常不相同，因此设计和改进翻译工具以在表示之间移动的问题是本研究的关键组成部分。 将严格审查中间表示的选择，并将开发适当的翻译工具。 这里的目标是推动适合微观和宏观尺度上多种制造工艺的中间格式。 最后，将开发使用由同一初始模型制造的宏观原型来测试和完善微结构设计的能力，并将仔细检查其在 MEMS 器件设计中的实用性。
