Vibrations, Contact Mechanics and Wear

In this research group, we tackle challenging dynamics and vibration problems of structures and their impact on the technical system under consideration. Our primary field of research is the modeling of (non-linear) system behavior. Another field of vibration research is vehicle dynamics. Based on characteristic road excitation, the vehicle multi-body dynamic model is excited, simulated and per criteria such as tire wear, driving comfort and safety evaluated and designed.

In our research on contact mechanics and wear, we deal with complex dynamic problems with friction. The friction between two objects allows the transmission of force between them such as the tire-road system (automobile) or the wheel-rail system (train). These systems are made manageable by means of model reduction methods and multi-scale simulations. A scale-independent modeling allows for the spatially resolved and detailed modelling of the friction behavior, which can also be efficiently represented numerically.

The contact between objects could lead to wear of these objects due to friction and relative displacement under certain conditions. The wear and tear caused hereby may be unwanted in most technical systems. The prediction of the wear based on the detailed friction model in consideration of the geometry changes of the objects in contact then allows the prediction of the service life of these objects.
