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 wind  turbines (WT).  In numerous research projects throughout past  decades,  drivetrain  technologies as  well  as  vibration  analysis  of  WTs and their drivetrain components  have  been  continuously developed.

For the improvement of the reliability of the gearbox of a WT 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.

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 which is continuously optimized. This model is used in the product development process in the final stage for the optimization of the drivetrain design.

Aim of this work is, to use the model of the research nacelle and derive models that can be used in earlier 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 domain (mechanics, control, electronics and aerodynamics) as focus of the work
  • Load analysis with the existing model
  • Derivation of simplified models
  • Load analysis with the simplified models
  • Comparison of the calculation results of the simplified models with the complex model


  • 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

We look forward to your application by email:
