Abstract

ELECTROHYDRAULIC FORMING (EHF) is a high velocity forming process in which the electric energy stored in the capacitors is suddenly discharged between two electrodes submerged in a water filled chamber. During the discharge, the water between the electrodes vaporizes and creates a shock wave that is transferred to the blank using the water and forms it. One of the key parameters in ELECTROHYDRAULIC FORMING is the determination of the suitable position of the electrodes. In this research the effect of ELECTRODES POSITION in electrohydraulic free-forming is investigated using the finite element simulation. First, the experiments available in the literature are simulated using the software ABAQUS/ Explicit and compared with the experimental results, which show good agreement. Then by changing the position of the electrodes, the effect of their position on the FORMABILITY and THICKNESS DISTRIBUTION of the blank is investigated. The results indicate that formation of a component is only possible in limited positions of the electrodes and there is a position for the electrodes that not only improves the sheet thickness but also decreases the possibility of the failure.
