摘      要：An integrated structural strength analysis method for a Spar type floating wind turbine is proposed in this paper,and technical issues related to turbine structure modeling and stress combination are also *** NREL-5MW ＂Hywind＂ Spar type wind turbine is adopted as study ***-domain dynamic coupled simulations are performed by a fully-coupled aero-hydro-servo-elastic tool,FAST,on the purpose of obtaining the dynamic characteristics of the floating wind turbine,and determining parameters for design load cases of finite element *** design load cases are identified,and finite element analyses are performed for these design load *** structural stresses due to wave-induced loads and wind-induced loads are calculated,and then combined to assess the structural strength of the floating wind *** feasibility of the proposed structural strength analysis method for floating wind turbines is then validated.
