Dynamics

Dynamic simulation methods are an integral part of the development process, starting from single components to the full vehicle. The interaction between various components significantly affects the dynamic and acoustic behavior of a vehicle and therefore also the driving comfort, the durability. A key advantage by using these CAE methods is that they are often superior to physical tests with respect to development time and costs as well as the "understanding of complex system behavior". These results show high potential of improvement and optimization.
