Bachelor-/Master Thesis: Modelling of journal bearings in innovative planetary gearboxes of wind turbines

Webseite Chair for Wind Power Drives

The Chair for Wind Power Drives researches the behaviour of drive systems in modern multi-megawatt wind turbines. The research objectives are to increase the availability, robustness and energy efficiency of wind turbines and to reduce the energy costs. For this experiment’s with software simulation tools and modern test benches are combined.
The use of journal bearings in planetary wind turbine gearboxes is becoming the new standard in the wind industry. The change from rolling bearings to journal bearings has the advantage of higher power density, which can further increase the efficiency of wind turbines. The implementation of a new generation of drive systems in wind turbines through the use of journal bearings is already being strongly promoted by the industry, but has so far posed the challenge of component reliability. Therefore, the aim of this work is a simulation-based wear analysis and reliability prediction of journal bearings for the use in innovative drive systems of wind turbines.


  • Research the state of the art of wind turbine drives and journal bearings.
  • Creation of simulation models (MBS, EHD) of journal bearings and assessment of the results.
  • Develop a concept to reduce the complexity of a journal bearing model, ideally by using stiffness and damping matrices.

Your profile:

  • Very independent and reliable way of working
  • High interest in wind energy, drive technology and interdisciplinary issues along with a high level of commitment
  • Previous knowledge of journal bearing technology and simulation is advantageous, but not essential

What We Offer:

  • A bachelor’s / master’s thesis with industry-related topics and clear relevance, as well as the opportunity to help shape a climate-neutral future
  • Adaptation of the exact topic to the competencies of the applicant
  • Intensive support in a highly motivated, interdisciplinary team with a very good working atmosphere
  • Direct start possible
