摘要： This paper constructs a coupled aero-hydro-elastic-servo simulation framework for a monopile offshore wind turbine (OWT). In this framework, a detailed multi-body dynamics model of the monopile OWT including the gearbox, blades, tower and other components (nacelle, hub, bedplate, etc.) has been explicitly established. The effects of pile-soil interaction, controller and operational conditions on the turbine dynamic responses are studied systematically in time domain and frequency domain. The results show that (1) a comprehensive drivetrain model has the capability to provide a more precise representation of the complex dynamic characteristics exhibited by drivetrain components, which can be used as the basis for further study on the dynamic characteristics of the drivetrain. (2) The pile-soil interaction can influence the wind turbine dynamic responses, particularly under the parked condition. (3) The effect of the pile-soil interaction on tower responses is more significant than that on blade responses. (4) The use of the controller can substantially affect the rotor characteristics, which in turn influences the turbine dynamic responses. (5) The tower and blade displacements under the operational condition are much larger than those under the parked condition. The model and methodology presented in this study demonstrate potential for examining complex dynamic behaviors of the monopile OWTs. To ensure accuracy and precision, it is imperative to construct a detailed model of the wind turbine system, while also taking into account simulation efficiency.
