Optimisation of component performance via structuring

Abstract

Abstract. Ecological and economic reasons are forcing industry to improve efficiency and to save energy and resources by reducing product weight. In current product designs often insufficient geometric stiffness of the part prohibits exploiting the full potential of weight reduction offered by modern materials. Ideally adapting the geometry to the load profile by implementing appropriate structures often allows a wall thickness and weight reduction and improves the acoustic properties. To enable a target-oriented design, structures manufactured by working media and working energy based forming technologies were analysed.

Structuring by electromagnetic forming and by forming with an elastomer punch as a tool for component optimisation regarding mechanical stiffness and acoustic performance

“…For this reason, application examples of EMF have been limited to small and medium sized parts and part areas up to now. However, recent developments at the Fraunhofer IWU [39] and in China [40] focus on extending this process limit via enhancing the conventional EMF by a sequential -i.e. a stepwise -manufacturing approach.…”

New lightweight construction prospects enabled by hydroforming

“…for part personalisation. The implementation of appropriate stiffening structures allows using a smaller wall thickness of the sheet and thus reducing weight while increasing the load capacitance [13]. The spectrum of possible structure geometries included regular patterns as shown in Fig.…”
