- Abstract
Draw-bending technology enables the production of load-adapted parts for lightweight construction applications. Its flexibility is particularly advantageous for small series production. In this study, the feasibility of introducing additional secondary forming elements to increase bending stiffness is investigated using finite element simulation. For this purpose, different bead geometries are designed and analysed by a numerical model of the draw-bending process. The process is evaluated based on the drawing force, the equivalent plastic strain and sheet thickness reduction. Finally suitable bead geometries are selected for future experimental investigations. The analysis shows that the challenge in optimisation lies between achieving the desired highest possible bead, which increases the stiffness and dimensional accuracy of the resulting profile, and the technological limitations due to the formability of the material. Under the current process conditions, the choice is limited to beads with a height of less than 20 mm. This study provides a basis for future research to optimise the bead design and improve the process parameters in the manufacturing process.
