摘要
海上浮式风力机在风浪作用下，支撑平台产生六自由度运动，诱导风力机叶片结构受力复杂。以DTU10MW单柱式浮式风力机为研究对象，根据IEC标准，联合使用FAST软件和ABAQUS软件计算不同载况下叶片在气动载荷、惯性载荷和重力载荷联合作用下的力学特性。研究发现：叶片的主要承载部分是叶肩附近的主梁区域以及叶片根部；风力机正常工作时，叶片极限载荷出现在额定风速的载况下；叶尖变形主要发生在与风轮平面垂直的法向方向上。
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.
