Under the action of wind and waves, the offshore floating wind turbine produces a six-degree-of-freedom movement on the support platform, inducing the wind turbine blade structure force complex. Taking DTU 10 MW singlecolumn floating wind turbine as the research object, according to the IEC standard, the mechanical properties of the blade under the integrated action of aerodynamic load, inertial load and gravity load under different loading conditions are calculated by combining FAST software with ABAQUS software. It is found that the main carrying part of the blade is the main girder area near the blade shoulder and the blade root;the blade ultimate load for the normal operation of wind turbine appears in the rated wind speed conditions;the deformation of blade tip occurs mainly in the normal direction perpendicular to the wind wheel plane.
