Webseite Chair for Wind Power Drives

The Chair for Wind Power Drives researches the behavior of drive systems in modern multi-megawatt wind turbines. Research goals include increasing the availability, the robustness  alongside energy efficiency of wind turbines as well as lowering the cost of electricity. For this purpose, software development tools and modern system test benches are used in a network.

For the improvement of the reliability of the gearbox of a wind turbine it is very important that there is a fundamental knowledge of the prevalent loads so that it is possible to consider them in the early stages of the product development process. A new scientific project at the CWD identifies dynamic loads which are a result of failures in the electrical power grid. In addition to that there will be an investigation of the dependency of those loads in relation to the chosen drivetrain concept. In the project there will be  investigations based on experiments on a WT test bench as well as a multibody simulation. One target of the project is the enhancement of the existing multibody simulation model in regard of the high speed shaft of the WT-gearbox. This location of the gearbox is chosen to be the focus of the enhancement since the significant load events resulting from the electrical grid failures are expected to occur there.


  • Familiarization with the existing multibody simulation model in SIMPACK
  • Development of new multibody simulation component models (especially cylindrical and tapered roller bearings) in SIMPACK
  • Integration of the component models into the existing overall model
  • Analysis of the occurring bearing loads


  • Motivation to work independently on technical questions in the field of drivetrain technology
  • Prior knowledge of multibody simulation in SIMPACK advantageous
  • Previous knowledge of the dynamics of wind turbines desirable

We offer:

  • Immediate start and rapid progress of the thesis
  • Intensive supervision
  • Flexible working hours in a young and motivated team

We look forward to your application by email:
