Abstract Details

2021, Doctor of Philosophy, Ohio State University, Mechanical Engineering.
Digital manufacturing is the use of an integrated, computer-based system comprised of simulation, 3D visualization, analytics, and collaboration tools to simultaneously create product and manufacturing process definitions. Digital manufacturing has become more feasible with the rise in the quantity and quality of computer systems. The advantage of digital manufacturing is the ability to modify or create manufacturing procedures within a virtual and controlled environment before being physically implemented. This enables the designers to see the results of their procedure before investing in physical products. The focus of this work is digital manufacturing of automotive wire harnesses. Current digital manufacturing software lack the ability to accurately simulate flexible components such as cables, hoses, and harnesses. The specific purpose of this work is to develop experimental procedures to characterize wire harnesses and obtain homogenized material properties for incorporation into digital manufacturing software. Experimental procedures are presented to characterize harness components and harness bundles. The different sizes of the components and various possible combinations of harness bundles make it difficult to experimentally characterize each one of them. Hence, limited experiments were conducted, and analytical models are proposed to characterize the components and use the available test data to validate the models. This research can fundamentally change the way harnesses are manufactured, designed and assembled. The experimental characterization and analytical models will help in harness routing, designing correct harness lengths to reduce vibration and rattling, residual stresses, and mechanical failure
