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 projectthere 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 this work there will bean analysis of the needed level of complexity for gathering sufficient results. One example for varying the level of complexity are the shafts of the drive train. These can be implemented in the MBS model as rigid, simplified with a few nodes or as complex FE bodies.


  • Familiarization with the existing wind turbine multibody simulation model in SIMPACK
  • Familiarization with the existing level of complexity
  • Development of simplified or more complexmultibody simulation component models e.g. shafts, bearings, gear wheels, … inSIMPACK
  • Running simulations with a defined load case
  • Comparison of simulation results e.g. regarding loads in the bearing. Calculation of the deviation between the system models result with the complex and the simplified component model
  • Deduction of recommendations for the level of complexity of specific component models in the MBS systems model


  • Motivation to work independently on technical questions in the field of drivetrain technology
  • Prior knowledge of multibody simulation in SIMPACKadvantageousbut not necessary
  • 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
