Evaluation of thruster vibration with virtual modelling


Customer: ABB Marine Oy


Conventional modal testing is practically impossible in challenging operating conditions.


VTT and ABB developed FE-models which took into account the most significant factors and phenomena affecting on
the vibration behaviour of the Azipod thruster in real operation conditions. The results were verified by full-scale experiments.

  • Faster R&D process with development and verification of new modelling methods
  • Elimination of prototype and pilot stages
  • Reduction in validation resources
  • Immediately revealed trivial design errors
