Abstract：

The schemes of direct forming and double stamping for car hinge were compared and analyzed by means of numerical simulation with Dyanform software.The results show that the adequate stretch of the material can be acquired with a few wrinkling and the part can be adequately strengthened in double stamping.The blank shape was optimized in view of the double stamping.By simulation,it is found that the blank-holder force is the main influence factor for the forming quality.Influence of different blank-holder forces on forming quality was studied and the best optimum blank-holder force was obtained.On the basis of the analysis result,the mould was designed which produced the qualified products.
