Learning from nature: Topological component optimization

Topology optimization permits the laws of natural evolution to be applied to component design. This involves determining the optimum distribution of material, also in terms of stresses, for predefined overall structural dimensions. The objectives of such optimization may vary. For example, optimization of rigidity may be one objective, whereas reducing the weight or dislocating the resonant frequency may be others. Areas of application for topology optimization include the conceptional determination of optimum component geometries, for example of frame structures or rib arrangements. CLAAS GUSS uses the Hyperworks package of software. The use of topology optimization software for component development results not only in optimized components, it also considerably speeds up the concept development phase, which means a major time advantage for our customers. The prerequisite, of course, is that the structural dimensions and the imposed loads and bearings are known. Casting as a production process is ideally suitable for implementing the sometimes highly complex proposals developed out of topology optimization in an appropriate form. However, topology optimization does not deliver a finished component design, just a proposal which then has to be developed into a functional component which is capable of being produced. This, in turn, is based on the knowledge of the foundry in respect of the production process and the knowledge of the customer in respect of the function.
