3、 caused by replacing DC04 steel with DC01 for the steel used for a door outer panel,the differences in mechanical properties and forming limits of the two materials were analyzed,and the forming process research of the door outer panel suitable for Iron and Steel products of Ansteel were carried out
4、 by forming simulation software.The results showed that the reduction of the plastic strain ratio r and the ultimate strain in the double tensile deformation zone would deteriorate the formability of the material and greatly increases the difficulty of the matching design of the material and the mol
5、d.The risk area predicted by the simulation was consistent with the actual stamping situation,which proved the accuracy of the simulation model,through the flexible design of drawbead and their resistance coefficients,stamping defects were effectively controlled,and the order quantity and applicatio
6、n stability of Ansteel products were significantly increased.Key words：outside panels of vehicle doors；stamping；wrinkling；cracking；simulation，。，、1，。，、2023 1 ANGANG TECHNOLOGY 439 28-2-4，CAE、，5。，。1 1.1 1，860 mm 1 170 mm 0.7 mm，DC04 DC01，。1 Fig.1 Outside Panels of Vehicle Doors 1，。，4，。1.2，CAE，Zwick Z1
