| Abstract: | To meet the demands of large size auto panel stamping and realize the coordination between sheet metal and auto part, the sensitive material parameters of high strain area must be determined on the basis of deep analysis to the forming feature of auto part. Through material mechanical test and forming limit analysis, the forming feature and sensitive material parameters of side frame panel are studied. It is shown that the deformation of high strain area belongs to bulging-deep drawing state. N value and r value are main sensitive material parameters which affect the forming quality of side frame panel. |
