| Abstract(E) | This study proposes a novel image-based shape generative model for automotive thin sheet metal components that generates internal shape under geometric shape constraints. By representing boundaries with B-spline curves and internal shapes as differential height maps, the method ensures consistency at the edges and enables diverse shape generation even with limited datasets. The results demonstrate the model's practical applicability and ability to produce varied boundary-conforming shapes. Applied to a vehicle hood inner panel, the generated shapes were successfully integrated into the actual vehicle FE model with only some modifications. |
