Abstract

Real-Time-Substructuring is a Hardware-in-the-Loop technique in the domain of structural mechanics, which combines physical tests with simulations. Applied to noise, vibration and harshness problems, Real-Time-Substructuring allows testing components of complex systems and their effects under realistic boundary conditions. The method can be used in cases where the setup of the full system in the laboratory requires high efforts and costs or where the virtual component is modified frequently during the design process. The Hardware-in-the-Loop concept allows to take into account non-linear effects of the physical component as well as effects, which are not included in the model, such as temperature changes during the test. Real-Time-Substructuring can enable a rapid prototyping approach as modifications on the physical component show direct acoustic and vibrational effects on the physical system.

In the talk, current research on Real-Time-Substructuring at the Chair of Applied Mechanics at the Technical University of Munich will be presented. A use case, which is currently worked on, is the design process of an automotive transmission crossbeam. Additionally, control strategies for Real Time Substructuring, which are used at the Technical University of Munich will be presented.
