【Abstract】 In view of the characteristics of the large motion response of the existing offshore floating wind turbine foundation under the action of wind and waves.Based on the hydrodynamic theory,analyzed the characteristics of the common offshore platform and summarized the hydrodynamic conditions that the excellent wind turbine needs to meet,so a new structure of floating foundation was design.Based on the numerical simulation software,the important parameter response of the new floating foundation were analyzed in frequency domain and time domain,and compared with the commonly semi-submersible floating foundation. The results show that the design principle of the new floating foundation is correct,and the overall structure is reasonable and feasible,so that the performance of the wind turbine is more excellent,and the new floating foundation can provide a more solid foundation for wind turbine,which can be used for reference in the construction of practical wind turbine foundation.更多还原
