Stringer Sheet Forming

Stringer Sheet Forming.

Abstract

Load carrying sheet structures are often stiffened by stringers or ribs. If they are also required to feature complex curvatures their manufacture becomes quite elaborate. Either spatially curved joints or time and energy consuming manufacturing processes have to be put up with. Sheet metal hydroforming is a deep drawing process in which the punch is replaced by a pressurized liquid medium forming the workpiece into a die. Since the pressure side of the workpiece is in no contact to solid parts of the tool, hydroforming can be applied to the forming of already stringer-stiffened sheets. The presented article addresses chances and challenges of this novel process chain and discusses architecture as a possible field of application.
