Investigations on forming and joining within the process chain car seat

Project Status: finished


The research project is focused on fundamental investigations on forming and joining of advanced high strength steels within manufacturing of lightweight car seat components in close-to-production quality. These new steel grades exhibit high specific strength levels at good formability compared to mild steels. Thus, promising material performance is expected considering an application in crash relevant structural components. In the final project phase, a complex car seat component was designed and technologically optimized with respect to forming and joining issues utilizing FE-based process simulation. Thus, significant mass saving and weight reduction were achieved. The applicability and transferability of the virtual process chain were demonstrated by a simultaneous validation procedure.
