Abstract：To optimize drawbead parameters in stamping processes，a simulation model is established by using Autoform，withtheresistancecoeficientastheevaluationcriterion.Orthogonal testingandvarianceanalysisare employedtoinvestigate theinfluencelawsof9parametersondrawbeadresistance.Theresultsreveal that parameters such as thetop filet radiuson theinflowsideof theconcave drawbeadand the height of theconvex drawbead significantlyinfluencedrawbeadresistance，whilethewallangleandbottomcornerradius haveminimal impact.In engirering，regulating the keyparameters canreduce defects suchaswrinklingand cracking，thereby improving mold debugging efficiency and lowering production costs.
