Abstract
In order to meet the future needs of ever-shorter device development processes, Fraunhofer IWU has developed a smart way to build an "optimal" truss structure using bionic methods. In the process, rigidity calculations and multi-criteria optimization, including pre-processing, are automatically carried out. The optimization results in various Pareto optimal structures which are then automatically generated in CATIA-V5, and presented as a set CAD model in order to be able to conventionally continue processing. The optimization methodology developed as well as the necessary conditions are described in this article, and explained with examples.
