The purpose of this study is to predict quantitatively the forging load of a large forged product using the power curve of hydraulic press. In previous forging analysis, it has been assumed that the die speed is constant during the forging process. However the die speed of hydraulic press is actually defined with the power curve, the relationship between die speed and press load. The change of strain rate having a direct relationship with the die speed affects the forging load. So it is necessary to consider the power curve to predict the forging load. In this study，the power curve was determined by measuring the die speed and press load through the several shop tests. According to FE analysis results, the forging analysis result with the variable die speed by the power curve had a good agreement with a measured final forging load within about 5% deviation, whereas the forging analysis with constant die speed overestimated the measured final forging load about 20%.
