9631590 Hu This GOALI award is for the development of an industrial-university cooperative relationship between Variation Systems Analysis, Inc. (VSA, Inc.), and the University of Michigan in jointly developing manufacturing process simulation methodologies for deformable part assembly. A Ph.D. student from the University of Michigan, under the guidance of an academic advisor and an industrial mentor, will (1) gain experience in manufacturing process simulation; (2) develop a new, generic mechanistic variation simulation methodology for deformable part assembly; (3) validate the newly developed variation simulation methodology by comparing with of the art techniques; and (4) apply this methodology to assembly fixture configuration design. Manufacturing process simulation, in particular, variation simulation, can provide valuable knowledge about the characteristics and capability of the process, thus helps manufacturers design better processes to deliver quality products in a timely fashion. However, currently available variation simulation methodologies are not applicable to deformable part assembly processes because these methodologies are based on rigid body assumptions. Deformable part assembly processes are widely used in manufacturing automobiles, aircraft, furniture, and appliances. The mechanistic variation simulation methodology will greatly enhance the scientific understanding of deformable part assembly product/process design.

小行星9631590 这个GOALI奖是为了发展变化系统分析公司之间的工业-大学合作关系。(VSA，Inc.），与密歇根大学共同开发可变形零件装配的制造过程模拟方法。 博士学位来自密歇根大学的学生，在学术顾问和工业导师的指导下，将 (1)获得制造过程模拟的经验; (2)开发一种新的、通用的变形零件装配机构变化仿真方法; (3)通过与现有技术的比较，验证新开发的变化模拟方法;以及 (4)将此方法应用于装配夹具的配置设计。 制造过程仿真，特别是变化仿真，可以提供有关过程特性和能力的有价值的知识，从而帮助制造商设计更好的过程，以及时交付高质量的产品。 然而，目前可用的变化模拟方法不适用于可变形零件装配过程，因为这些方法是基于刚体假设。 可变形零件装配工艺广泛应用于制造汽车、飞机、家具和电器。 机构变化仿真方法将大大提高对可变形零件装配产品/工艺设计的科学认识。
