| Research Abstract |
The typical size of the horizontal axis wind turbines is increasing in these decades, which brings about the closed values of the eigen frequencies of the turbine structures and the rotor rotation frequencies. It may lead to the resonance occurrence as well as the decrease of the turbine life time due to the increased amplitudes of the turbine oscillation. In the present study, we have developed a “fluid-oscillation coupled analysis model” which can be a design tool for the large wind turbines. We also examined the effects of the blade oscillation and the turbulence characteristics of the inflow wind on the fatigue loads of the wind turbine.
