The main research contents and results embody as follows: According to the two typical drawing simulation of box part and cylindrical part, it is arrived a main method in improving sheet metal forming ability as follows: in the qualification of not initiating the wrinkle, brought more particle in fillet region into straight flange region, in the meantime cause the particle in the straight flange region run more distance towards the middle region which resistance is the minimal. A theoretical study of new technique is developed in sheet metal forming base on virtual power principle. The results indicate that decrease the equivalent stressσ, improve the lubricate state in contact surface, decrease the area, the normal contact stressσn and the equivalent strain velocityεin initial principal deformation region, adjust and optimize the particle cycle flow of work piece flange face will greatly increase the sheet metal draw ability in room temperature conditions. And drawing hole forming technology is araised based on the analysis above.
