大型风力机叶片仿生叶脉结构设计及性能分析
Design and Performance Analysis of Bionic Blade Vein Structure for the Large Wind Turbine Blade
摘要
Abstract
With reference to the characteristics of plant blade vein distribution,a new wind turbine blade layup design approach is developed by taking advantage of the similarity between plant leaf veins and blade structural functions in order to cope with the high structural performance demand given by the large-scale wind turbine blade.Using computational fluid dynamics and the finite element approach,the modal,structural strength and stability analyses of the bionic blade are carried out.The results show that:compared with the traditional blade,the intrinsic frequency of the bionic blade is increased and the torsional characteristics are stronger.The tip displacement of the bionic blade is greatly reduced,and the surface stress value is reduced,but the web stress is increased.The first six orders of flexion factors of the bionic blade are all increased compared to the conventional blade,suggesting that the plant leaf vein structure is beneficial for improving blade stability.关键词
