The main defect of the inner-hood is break, which was obtained by the numerical simulation of it’s forming process. The main impacted parameters of sheet metal forming process are corner radius of die, friction coefficient, clearance between punch and die and the height of drawbead. The maximum impact of the break of forming factors was drawbead high, followed by the die gap, die edge and the friction coefficient which were obtained by the four factors orthogonal optimized simulation. The comparison between the results of numerical simulation and actual operation proved the accuracy of the numerical simulation.
