Tribology Systems

Tribological systems make an essential contribution to fulfilling functions of modern technical systems. Designing and optimizing tribological systems has always been a challenge due to complex interactions in friction contact. Our research is therefore geared towards methods for numerical and experimental modeling of tribological systems and their validation taking multi-physical and multi-scale factors into account. We develop suitable validation methods and friction models with emphasis on clutches, brakes as well as plain and roller bearings and from this derive optimized tribological systems.

Research Focus:

  • FEM Simulation-model of friction and wear in dry and wet tribological systems
  • Development of thin-film sensors for under mixed-friction condition
  • Reducing friction and wear of tribological systems by means of modified cutting tools
