摘要

风力机超大型化发展将引发叶片质量与结构性能需求相悖,为此参考植物叶片的叶脉结构,提出应用于15 MW风力机叶片的仿生内肋构型,并结合铺层设计实现叶片轻量化及结构强化设计。通过单向流固耦合的方法,对叶片进行模态、刚度、强度及稳定性分析。结果表明：仿生内肋构型可提升叶片挥舞与扭转刚度,避免叶片与塔架碰撞,但摆振刚度有所降低;仿生叶片的表面应力较传统叶片均有所提升,但并未达到材料的极限;仿生叶片的屈曲因子有所提升,且并未发生叶片整体屈曲,满足稳定性要求。

Abstract

The development of super-large wind turbines will lead to the contradiction between the blade quality and structural performance requirements of blades. Therefore, referring to the leaf vein structure of plant blade, a bionic internal rib configuration for 15 MW wind turbine blade is proposed, and combined with the pavement design to realize the lightweight and structural reinforcement of the blade design. The modal, stiffness, strength and stability of the blade are analyzed by the one-way fluid-solid coupling. The results show that the bionic internal rib configuration can improve the blade flapwise and torsion stiffness, avoiding the collision between the blade and the tower, but the edgewise stiffness is reduced; the surface stress of the bionic blade is improved compared with that of the conventional blade, but they do not reach the limit of the material; the buckling factor of the bionic blade is improved, and the overall buckling of the blade does not occur, so it meets the stability requirements.
