Abstract

The quality of structural optimisation in product design depends on the intuitively selected initial geometry and is a result of the designer's experience. The improvement in weight reduction or stiffness gain, which is within reach by current optimisation systems, can only be modest. Topology optimisation, however, needs only few boundary conditions for generating a complete preliminary geometry automatically. This rough design can be used as the basic shape for further optimisation strategies, e.g. shape optimisation. So the target should be the integration of topology and shape optimisation in a CAD-System in order to produce a tool which supports the complete design process. This contribution deals with several applications of an integrated topology and shape optimisation system.
