WebFor floating wind turbines, Ghafari et al. (2024) developed a hybrid floating platform based on Wavestar. The effect of the diameter and damping coefficient of the wavstar on the vibration damping effect was tested. The structure includes a semi-submersible platform, deck, connecting arm, and wavestar (see Fig. 4 (a)). Experimental results show that the … WebFigure 4: SDOF system response below, at, and above natural frequency of system. The following can be observed: Below the natural frequency, the base and mass move together in phase. At the natural frequency, the base and mass move 90 degrees apart, which creates a kind of “bucking” motion causing the high levels of vibration.
