Lightweight Design

Competences of the focus group Light Weight Design

The focus group Light Weight Design develops and researches weight-optimised and usually very highly stressed, partly safety-critical structures. The competences here range from conception to design, simulation, dimensioning, mechatronics and measurement technology to prototype construction. Applications are found in special and rail vehicles, in aircraft and drones, and increasingly in highly dynamically loaded mechanisms and systems. The simulation of extremely short-time processes in the millisecond range on the institute's own computing cluster with more than 400 CPUs using explicit hydrocodes is therefore another focus of the group, together with fluid-structure interaction analyses (FSI), as is the multidisciplinary optimisation of structures. Among other things, new algorithmic methods such as machine learning are being researched in order to model highly complex physical phenomena of the most diverse kinds more efficiently and accurately, with the large amounts of data being reduced with the help of Reduced Order Models (MOR). Finally, the group is also active in the field of aeroelasticity, i.e. the interaction between aerodynamic excitation and structural vibrations such as those that occur in the rotor blades of wind turbines. The preparation of expert opinions and damage analyses on the strength of even welded structures, together with dedicated knowledge of standards in the areas of application, round off the range of expertise.
