Method for considering the process chain in the design process of clinched components
Sven Martin, Thomas Tröster
download PDFAbstract. To ensure a high quality design of joined components, it is essential to consider the joining process chain since deviations in the process chain can lead to failure of the component. Since eliminating the cause of process deviations can be very cost-intensive, it is desirable to ensure component and joining safety by making small changes. A method to regain all safety factors after a change in the process chain by making minor adjustments in the joining process and the design is presented here. The method is demonstrated on a clinched component consisting of a U-profile and a strike sheet.
