The Dynamics and Friction department works on non-linearities and contact conditions of dynamic problems in mechanical engineering, e.g. vibrations in drives or deep drilling processes. Despite research, friction remains complex - even with lubricants that create new challenges. A key factor is the amount of fluid in the gap: studies show that even minimal amounts can lubricate effectively. This knowledge flows into the modeling of adhesive flows or sustainable solutions for fluid reduction. The research combines experiments with mathematical analogies to flows in narrow gaps in order to develop ecologically sensible approaches. Analytical methods can also be transferred to cell biology issues.
