摘　　要：随着陆上风电和海上风电的叶片越来越趋向于大型化,减小叶片载荷和质量,提高叶片气动性能成为十分重要的设计内容。叶片越长,叶片变形对叶片性能的影响也越大,因此采用叶尖挥舞方向变形对叶片性能进行评估,基于叶素-动量理论,实现气动与结构的耦合设计,缩短叶片设计周期。以5.8 MW、85 m叶片为例,叶片挥舞方向变形为14.5 m,符合设计要求。As the onshore and offshore wind turbine blade are becoming larger and larger,reducing the loads and mass of the blade and improving aerodynamic performance are very important for the blade design.The longer the blade is,the greater the effects of blade deformation on the blade performance will be.The flap-wise deformation of the blade tip is adopted to evaluate the performance of the blades.Based on the blade element momentum theory,the coupling design of aerodynamics and structure is realized to reduce the blade design cycle.Taking the 5.8 MW,85 m blade as an example,the tip flap-wise deformation is 14.5 m,which meets the requirements of the blade.
