Abstract：

In order to improve quality of car roof in the drawing process, the finite numerical simulation was carried out by sheet metal forming analysis software Dynaform. The influences of die clearance, friction coefficient, BHF and drawbead number on forming quality of car roof were studied. The forming process parameters of product were optimized by CAE analysis and orthogonal experiment, and the main factor values affecting drawing forming quality were determined. Therefore, the number of actual test was reduced, and the efficiency of the die manufacturing was improved. The results show that drawing defects are predicted by the numerical simulation analysis CAE, product quality of simulation and experimental is consistent, errors are within the acceptable range, and a qualified part is obtained by numerical simulated process.
