000015281 520__ $$2eng$$aThe automotive industry is in need of fast crash test simulations. Instead of using faster hardware, a modern approach consists of reducing the system size of the underlying equations while retaining important system properties and controlling the approximation error. Linear variants of this so-called model order reduction are well explored and therefore used as much as possible. In a car crash scenario, some parts of the automobile exhibit large deformations, whereas others experience mostly small vibrations. We therefore identify linear behaving parts of the model and separate/reduce them with modern, improved Component Mode Synthesis approaches. The interface plays a crucial role in the speedup, hence an interface reduction is also required. The application to a kart model delivers promising results. Additionally, a workflow is developed, which can be adopted to a full car model consisting of more than one million degrees of freedom.
