Optimization of Draw-In for an Automotive Sheet Metal Part An evaluation using surrogate models and response surfaces
Författare
Summary, in English
In the present paper, an optimization of the draw-in of an automotive sheet metal part has been carried out using Response Surface Methodology (RSM) and Space Mapping technique. The optimization adjusts the drawbead restraining force in the model such that the draw-in in the FE model corresponds to the draw-in in the physical process. The conclusion of this study is that Space Mapping is a very effective and accurate method to use when calibrating the draw-in of a sheet metal process. In order to establish drawbead geometry from the drawbead restraining force a 2D-model was utilized. The drawbead geometry found showed good agreement with the physical drawbead geometry.
