摘　　要：为掌握风力机叶片在不同风速下的偏移规律,了解变桨对叶片偏移的影响,研究了风力机气动载荷的计算方法,并充分考虑叶片稍部损失和根部损失,总结出一种较为完整精确的计算步骤。基于Bladed软件,建立2 MW水平轴三叶片风力机模型,并以此为例,计算了稳态下的摆振(即平行于风轮平面的方向)载荷和挥舞(即垂直于风轮平面的方向)载荷,并对摆振方向和挥舞方向的偏移进行计算和分析,表明气动载荷使叶片产生明显的偏移现象。In order to master the blade deflection regularity of wind turbine under the various wind speeds, and find out the pitch-control impact on blade deflection, this paper studies the aerodynamic load calculation method of wind turbine, taking into account balde tip and root loss, and summarizing a more comprehensive and accurate calculation process. Based on Bladed software, 2 MW three-blade horizontal axis wind turbine model is established, whereby this research calculates the edgewise （ the direction of parallel to the wind wheel plane） load and flapwise （ the direction of perpendicular to the wind wheel plane） load under steady load, as well as the deflections on edgewise direction and flapwise direction. Calculation results show that the aerodynamic loads lead to obvious blade deflection.
