The model is based on kinematic and dynamic principles, with a focus on the multi-blade coordinate transformation, which is critical for simulating the behaviour of the rotor whirling modes in wind turbines. The research has two objectives: to investigate the interaction between the rotor edgewise whirling modes and the rotor speed harmonics, and to provide clearer graphs that explain the complex nature of this non-intuitive rotor dynamics. The paper concludes by highlighting the practical implications of the research findings, in particular the effectiveness of visualisation techniques in identifying and explaining unexpected interactions.application/pdfengContent from this work may be used under the terms of the Creative Commons Attribution 4.0 licence.Wind turbinesRotor edgewise whirling modesRotor speed harmonicsinfo:eu-repo/semantics/conferenceObject2024-06-17info:eu-repo/semantics/openAccess
