A new scheme for blank holding force (BHF) is introduced in order to apply more realistic BHF in simulation. The present study has been carried out for deep drawing processes of a washing-trough. Different blankholder gaps and separation forces simulate the blank holding process. The optimum blankholder gap and separation force are determined through a systematic approach. It is found that the wrinkling in the flange region of the blank increases with the augmentation of the blank holder gap. And the BHF increases owing to the elevation of the rigidity of the sheet metal. The simulated thickness with separation force is lower than that with the blankholder gap because the BHF is variable in the flange region. A comparison of the thickness and flange contour between the simulation results and experiment shows that the blankholder gap is better in the simulation of the BHF in sheet metal forming process.
