Abstract Summary
The study aims to investigate the effectiveness of tuned mass damper inerter (TMDI) for vibration enhancement of offshore wind turbine subjected to wind and wave forces. H2 optimization method is used to find the optimal parameters of the TMDI. Wind velocity is varied to examine the performances of TMDI under varying wind loads, where the wave is kept the same. In addition, the uncertainty of parent structure is considered to test the robustness of the TMDI. Its performance is compared with an optimal TMD system. It is found the designed TMDI is far better than the TMD system. In addition to vibration mitigation, TMDI has much higher effectiveness in energy harvesting.
