Abstract：

For three-dimensional model of simplified part, which is the front reinforcement plate of an automobile, finite element model and numerical simulation of the sheet metal forming were established by CAE analysis software Dynaform. Combining the orthogonal experiment with the numerical simulation result, the four process parameters involved in the forming process, such as blank holder force, friction coefficient, die clearance, stamping speed were selected as investigation factors, values from three different levels of every factor were selected in the orthogonal experiment. The minimum thickness after sheet metal forming process was selected as the quality indicator, and the influences of various factors at different levels on the simulation result and forming quality were analyzed. The results show that the descending order of influence degree on the minimum thickness for the stamping part is friction coefficient> blank holder force> stamping speed> die clearance. The best process parameters combination is blank holder force 300 kN, stamping speed 1000 mm·s-1, friction coefficient 0.10 and die clearance 1.35 mm, and its correctness and practicability were verified by experiment.
