Here, a new type of articulated offshore wind turbine (AOWT) structure was proposed for 50 m operating water depth, and the swing motion analysis model of AOWT was established. Adopting the aerodynamic-hydrodynamic coupled analysis method, the motion control equation was coded in time domain using the software MATLAB to analyze dynamic responses of AOWT under different environmental loads of wind, wave and flow. Then, effects of turbulent wind on the overall motion and load response of AOWT were further studied. The calculation results showed that AOWT has good motion and load performance under the rated wind speed and sea conditions, and meets the structural design requirements; compared with the steady wind, the mean value of AOWT response decreases significantly under turbulent wind, but its amplitude variation increases, and a larger resonance is induced within low frequency range. © 2022, Editorial Office of Journal of Vibration and Shock.
