Abstract

In sheet metal forming processes, one-stage production of conical-cylindrical parts with high accuracy is very difficult due to wrinkling and rupturing. Hydrodynamic deep drawing assisted by radial pressure is one of the most applicable procedures in sheet hydroforming process on the point of producing conical-cylindrical parts. In this paper, forming pressure path is investigated as one of the most important parameters of this process. The optimized pressure path is obtained utilizing a new procedure by combination of the finite element method using ANSYS/LS-DYNA and an optimization method using simulated annealing.
