The equation provided a theoretical basis for selecting the press tonnage during the forging process with liquid core. We constructed the relationship equation between the forming pressure and the other three factors in Origin. Fifty-three sets of forging parameters data were recorded including the solid-phase thickness, the reduction amount, the pressing speed and the forming pressure in each group. Four groups of the physical models of the multilayer gradient were also established under laboratory conditions. We mastered the deformation law during the forging process with liquid core. The significant factors were acquired by the range analysis which affected the values of the equivalent strain and the equivalent stress in the solid-phase region, the solid–liquid two-phase region and the liquid-phase region. Three orthogonal tests were designed to obtain the results with solid-phase thickness, reduction amount and pressing speed as three factors.
LIQUID SIMULATION SOFTWARE
