Research into structural optimization was primarily the responsibility of the C.I.K. Here, it was possible to fall back on many years of research in the field of topology optimization for additive manufacturing (cf. New Structure and OptiAMix). In this context, three of the five demonstrators were extensively redesigned and new solutions were developed based on the requirements. These range from a dedicated structural optimization (Figure 2, Part 5), a life cycle oriented optimization from automotive engineering (Figure 2, Part 1) to a combination of structural and thermal optimization (Figure 2, Part 3).
Especially in the area of coupled optimization of components for the integration of thermal management with structural elements, an important component for the application of additive manufacturing could be achieved within the scope of this project. The automated creation of optimal geometries for this purpose offers great potential for the material-saving optimization of heat- and structure-loaded components.
In 2018, research will focus on the field of structural damping of components. As a demonstrator, a mounting bracket for engine attachments will be machined here to increase the vibration-based fatigue strength.
