Giving a certain condition of reasonable shape of blank,draw beads and gradual fillet of die,numerical simulation of deep drawing for automotive headlight reflector was carried out in variable blank holder force.The results show that trough-type BHF is better for the drawing quality.Moreover,the best optimum load curve of BHF was obtained by simulation result and neural-net method.It is advantageous for achieving the accurate control of BHF in the deep drawing.
