| Abstract: | The forming process of side-hole flanging of an ellipsoid bottom part was present- ed; and the die structure design was completed based on the process calculation and pro- duction experiences. The deformation trend, equivalent stress and plastic strain distribution of different regions were predicted by the forming simulation of PAM-STAMP 2G software which provides the theoretical basis for the practical production, and the reference data for the further optimization of forming process parameters of sheet metal and the improve- ment of die structure. |
