Master Thesis: Numerical simulation of damping and stiffness of contact under dynamic excitations

Webseite Institute for Machine Elements and Systems Engineering

The Institute for Machine Elements and Systems Engineering researches the fundamental structural and tribological behavior of machine elements and represents it in experimentally validated model descriptions. These models are used to organize and analyze the behavior of technical systems in terms of functionality, losses, and noise emissions with a focus on drive technology. The developed models also serve as basis for the research and development of methods of Model Based Systems Engineering which are central elements of future industrial product development processes.

In order to model damping and stiffness of single contact in bearing, a transient hydrodynamical simulation under consideration of periodic excitation is needed on the first level.

The aim of this work is to develop and run CFD Simulations in Open FOAM for a single contact in bearing for different cases and to determine the physical damping and stiffness of the contact and validate them using new test rig in MSE.


  • CFD simulation of single contact in bearing element
  • Research on different vibrational models of contact
  • Numerical investigation on contact
  • Experimental validation of results with Tribometer of MSE


  • Independent and reliable work
  • Interest in Numerical simulation or acoustics
  • Open-FOAM and Programming experience is necessary

We offer:

  • Possibility to start immediately after interview
  • Intensive mentoring
  • Good and supportive working climate
  • Research experience for a future career in academics or industry

We look forward to your application by email:
