The objective of this research was to develop a computer- controlled method for the cold forming of ship frames, i.e., large steel beams. The approach taken was to develop a bench scale model of a beam-bending apparatus that can shape ship frames by applying pure bending moment to the members and eliminate out-of-plane deformation by computer routines that correct incipient errors detected during the bending. Successful completion of the project can potentially revitalize the ailing U.S. shipbuilding industry by vastly reducing the costly customization process, thereby reducing the costs of shipbuilding. From this project the Maritime Administration expects to obtain specifications for a full-scale beam bender. Overall, project utilization is significant in that a federal agency, the Maritime Commission, is using the research results; in addition, attitudes of industry are being modified through awareness of the ultimate potential of the techniques being developed.
