Webseite Chair for Wind Power Drives

The Chair for Wind Power Drives at the RWTH Aachen University conducts research in the field of drivetrain technologies for windturbines (WT). In numerous research projects throughout past decades, drivetrain technologies as well as vibration analysis of WT sand their drivetrain components have been continuously developed.

For the improvement of the reliability of the gearbox of a WTit is very important that there is a fundamental knowledge of the prevalent loads so that it is possible toconsider them in the early stages of the product development process.

In order to investigate the drivetrain loads and dependent of the stage of the product development process different levels of complexity of models for the mechanics, the control, the electronics and the aerodynamics can be used. Regarding the drivetrain mechanics e.g. a simple three-mass oscillator up to a complex multi body simulation (MBS) model can be used.

The CWD has a complex MBS model of a wind turbine research nacelle with models for the control, the power electronics and the aerodynamics whichis continuously optimized. This model is used in the product development process in the final stage for the optimization of the drivetrain design.

Aimof this work is, to use the model of the research nacelle and derive models that can be used in different stages of the product development of a WT drivetrain.


  • Familiarization with the existing MBS model of the research nacelle in SIMPACK
  • Familiarization with the existing systems model of the research nacelle including control, power electronics and aerodynamics in Matlab Simulink
  • Specification of a focus of the workin the field of MBS:
    • simplified models for the preliminary design
    • complex component models (e.g. bearings) for the optimization of the risk of damage
  • Load analysis with regard to the thesis focus
  • Evaluation and interpretation of the results
  • Derivation of possibilities for optimization in the WT design


  • Motivation to work independently on technical questions in the field of drivetrain technology
  • Interest in modelling and simulation
  • Prior knowledge of multibody simulation in SIMPACK advantageous but not necessary

We offer:

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