Development of bionic design concepts for structure optimisation of forming tools according to production and stress constraints

In the automotive industry, current design and dimensioning of forming tools and bearing tool components occurs according to guidelines. Possible interactions between arising loads as well as dimensioning are empirically estimated. Simulative computations, which are based on CAE-methods, are only realized in special cases. Therefore, most often current standards lead to oversized tools. In consequence, new studies based on CAE-analyses are supposed to investigate new possibilities to design forming tools and components optimized in their structure corresponding to the right distribution of forces and stress. This is made in order to increase reliability during the manufacturing process, as well as the tools' stiffness and contribute to decrease of investment costs.
