Considering the influence of different environmental factors, the dynamic responses of the structure are studied. Three dimensional potential flow theory was used to calculate the hydrodynamic characteristics of the structure, and the blade element momentum theory was used to calculate the aerodynamic load, the influence of foundation motion, wave surface elevation and friction damping of articulated joint were certainly considered. The control equation in the time domain is set up and the motion response is solved. It is shown that the aerodynamic load has great influence on the average response amplitude, including the average pitch angle, the rotor thrust and the tension of articulated joint. while the wave load is related to the variation of amplitude. The structure will produce a large coupling low-frequency response in the low-frequency range with wave and wind. Especially, under the action of turbulent wind, the coupling effect increases sharply.enhttp://rightsstatements.org/vocab/InC/1.0/Offshore articulated wind turbineBlade element momentum theoryAerodynamic loadCoupling effectTechnikIngenieurwissenschaftenCoupled response analysis of an offshore articulated wind turbine under different environmental loadsConference Paper10.15480/882.330810.15480/882.3308Fluiddynamik und Schiffstheorie M-8Other
