Design and optimization of addendum surfaces in sheet metal forming process. (English) Zbl 1137.74047

Int. J. Comput. Methods Eng. Sci. Mech. 8, No. 4, 211-222 (2007).
Summary: In the sheet forming process, addendum surfaces have an important influence on the formability of the workpiece. If the design of addendum surfaces is done manually with a CAD software, many corrections should be made according to experimental or/and numerical results. This study proposes an automatic procedure for design and optimization of addendum surfaces by using our fast inverse approach and two optimization algorithms. The present optimization procedure is applied to the Renault Twingo dashpot. The results show that the optimization calculation converges rapidly towards an optimal solution. The future work is to automatically (or semi-automatically) create the addendum surfaces with \(G^{1}\) continuity for the industrial workpiece with complex geometry.
