The application of dynamic vibration absorbers (DVA) to Wind Turbine (WT) towers has the potential significantly improve damping tower and nacelle responses, increasing thus reliability WTs. Tuned Mass Damper (TMD) is limited by requirement large masses, in association its installation location. In this study, two alternative concepts are considered. First, released from WT tower, using a low s...

The objective of this study is to mitigate, or even completely eliminate, the limit cycle oscillations in mechanical systems using a passive nonlinear absorber, termed the nonlinear tuned vibration absorber (NLTVA). An unconventional aspect of the NLTVA is that the mathematical form of its restoring force is not imposed a priori, as it is the case for most existing nonlinear absorbers. The NLTV...
