Influence of Pressure Plate Parameters on the Efficiency of Electrohydraulic Deformation of a Rigidly Clamped Workpiece

Based on mathematical modeling of the process of electrohydraulic sheet stamping, the influence of a pressure plate on the deformation of a workpiece rigidly clamped along its outer contour was studied. The influence of the thickness of the pressure plate and its internal diameter, in relation to the diameter of the cavity of the cylindrical discharge chamber, on the energy of plastic deformation of the workpiece and the shape of its deflection; parameters of the pressure plate on the pressure of hydrodynamic waves on the workpiece; and the shape of its deflection and the efficiency of using the energy stored in the capacitor bank for plastic deformation of the workpiece have been established.
