Abstract：The fully coupled aero-servo-hydro-elastic-linear foundation simulation tool is developed based on the recompiled FAST-SC-SSI, and the coupled linear spring is applied to simulate the soil-structure interactions (SSI). The reference offshore wind turbines is designed according to the NREL 5-MW baseline wind turbine and a monopile foundation. The parameters of tuned mass damper (TMD) in nacelle are designed based on the dynamic characteristics of monopile OWT with rigid and flexible boundaries. Reductions of the structural responses in the time and frequency domains are adopted to reveal the vibration control mechanisms of TMD and evaluate the influence of SSI on the TMD mitigation effects. Based on the performed investigations, it can be seen the significant influence of SSI on the reductions of structural responses, which should be emphasized in the design of TMDs for OWTs.
