Abstract:
The die profile on the drawing performance is invrstigaled by the optimization method. The optimization model based on the critical condition of wrinkling is established the optimization solution can avoid the accurrence of wrinkinp; and assure the smallest Fmax and the biggest deep-drawing ratio.
