Abstract：

A method for parametric modeling and automated design of drawbead was proposed to achieve real-time design, real-time update and parametric design. According to defined parameters of control points, the section curves were created by the orthogonal section method to avoid the undercut shape that easily appeared in the modeling of drawbead. The function of hybrid drawbead with the multiple shapes was implemented by segmenting the same drawbead, and the design flexibility of drawbead was improved observably. Through extrapolating the drawbead curve along the normal direction of binder, the ends of drawbead were designed smoothly. Based on the parameter association of CATIA and user defined feature (UDF), the UDF of the real drawbead was proposed and a system for parametric design of drawbead (DBDS) was developed, which realized the parametric creation and modification of drawbead. Through testing massive amounts of automotive cover panels, the method is proved to be reliable and accurate, which is appropriate for automated optimization design of drawbead.
