ABSTRACT
In order to achieve the wind-induced vibration response analysis and fatigue analysis, this study conducts the wind field simulations around tubular tower and rotating blades of typical pitch-controlled 1.25MW wind turbine structures, respec-tively. Based on field test data, there is a large difference between the turbulent wind spectrum for the rotating blades and classic wind spectrum adopted by the non-rotating blades and tubular tower. In this study, first, the auto and cross-rotational Fourier spectrums are deduced based on the physical mechanism, with particular focus on the influences of the rotational effect and the correlation between different points located on the same and different blades. Then, the Daven-port type coherence function is optimized. The high accuracy of the rotational Fourier spectrum model is verified by comparing with the real data. Relevant parameter analysis of the rotational Fourier spectrum is conducted. Finally, tur-bulent wind fields around the tubular tower based on the Kaimal spectrum and the rotating blades based on the rotational Fourier spectrum are simulated by means of the harmony superposition method. The results indicate that the calculated wind spectrums have good agreement with the target wind spectrums. Therefore, the proposed approach in this study is feasible for the turbulent wind field simulation of wind turbine structures.
