Abstract：

For the bottom bracket of the car, the general steps of simulating its stamping process numerically were introduced based on Dynaform software. Product formability was simulated by changing the blankholder force, blank shape and setting drawbeads, and then assumptions about wrinkle, fracture, thinning and other defects in sheet metal forming were conducted. Forming process and technical parameters of the product were determined by analysis on the simulation results. Experimental results show that the optimized blank is formed to achieve better quality with BHF 1000 kN, friction coefficient 0.125 and drawbead, and the rationality and feasibility of the numerical simulation parameters are verified. Furthermore, the times of actual test are reduced and the efficiency of the die manufacturing is improved.
