To determine the parameters of the discharge circuit of the electrohydraulic press for forming complex-shaped parts in a multipulse mode, it is sufficient to know the required discharge parameters at the stage of the complete formation of a part. To this end, we developed an engineering method of calculation, carried out its experimental evaluation using the example of forming the part type – a “side pillar of the car”. The algorithm to solve this problem is proposed, which involves finding the point of the blank surface – the most difficult for forming, determining the dominant factor in the process of electrohydraulic forming of such a point by calculation, comparing the calculated pressure with the experimental results and the calculation of the required energy level necessary for the full formation of the part.
