To optimize drawbead parameters in stamping processes, a simulation model is established by using Autoform, with the resistance coefficient as the evaluation criterion. Orthogonal testing and variance analysis are employed to investigate the influence laws of 9 parameters on drawbead resistance. The results reveal that parameters such as the top fillet radius on the inflow side of the concave drawbead and the height of the convex drawbead significantly influence drawbead resistance, while the wall angle and bottom corner radius have minimal impact. In engireering, regulating the key parameters can reduce defects such as wrinkling and cracking, thereby improving mold debugging efficiency and lowering production costs.
