GOALI/Faculty and Students in Industry: Variation Simulation and Planning for Deformable Part Assembly

该GOALI奖旨在发展变化系统分析公司（VSA, Inc.）和密歇根大学之间的工业-大学合作关系，共同开发可变形零件装配的制造过程模拟方法。密歇根大学的博士生，在学术顾问和行业导师的指导下，将(1)获得制造过程模拟的经验；(2)开发一种新的、通用的可变形零件装配机理变化仿真方法；(3)通过与艺术技术的比较，验证新开发的变化模拟方法；(4)将该方法应用于装配夹具结构设计。制造过程模拟，特别是变化模拟，可以提供有关过程特性和能力的宝贵知识，从而帮助制造商设计更好的过程，及时交付高质量的产品。然而，目前可用的变差模拟方法并不适用于可变形零件的装配过程，因为这些方法是基于刚体假设的。可变形件装配工艺广泛应用于汽车、飞机、家具、电器等行业。机械变差仿真方法将大大提高对可变形件装配产品/工艺设计的科学认识。

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.
