Detection and Elimination of Wrinkles on an Auto-Body Panel by the Binder Set Analysis 930515

This paper describes the capability of the binder analysis in Ford's three dimensional sheet metal forming program. Three real design examples illustrate that the program could detect buckling/wrinkling in auto-body panels during binder set (wrap). With revision of the binder surface design, the program predicted buckling/wrinkling on those panels disappeared. The computing time for each evaluation of the binder set of a panel is in order of minutes on a super workstation; therefore, it has been used as a design analysis tool.
