摘要：
Based on the theory of multi-body dynamics, the coupled analysis model named FAST-SC-MTMD of floating offshore wind turbine with multiple tuned mass damper(MTMD) is established in the recompiled FAST-SC. Taking the barge-type offshore wind turbine as research object, the parameters are designed using the recommended optimization formulas for MTMD in offshore engineering. Then, the mitigation effects of TMD and MTMD are evaluated based on the reductions of structural responses of the floating offshore wind turbine under stochastic environmental loads. It can be seen that the pitch frequency should be prior designated as the MTMD tuning frequencies and the MTMD should be mounted in the nacelle and platform, in order to mitigate the motions of the tower and floating platform effectively. © 2022, Solar Energy Periodical Office Co., Ltd.
