摘要/Abstract

摘要： 现代风力机叶片的大型化带来了设计和生产方面的诸多问题,叶片的静力实验是分析叶片结构稳定性的重要基础和验证手段。对中国科学院工程热物理研究所研发的100kW大厚度钝尾缘叶片进行了静力实验研究,分析了叶片在摆振和挥舞方向的屈曲特性和应变特性,通过对静力特性进行分析,探讨了叶片在载荷作用下的刚度及应变等性能特性,比较了叶片相对于传统尖尾缘叶片的结构性能优点。最后,将失效实验结果同设计值相比较,分析了产生误差的原因。

Abstract: Increasingly large-sized wind turbine blade brings many design and production problems, static experimental of blade is the important foundation and verification means, which can be used to analyze the structure stability of the blade. This paper presents the static experimental study of the 100kW experimental blade with flatback and thick airfoils, which was designed by project team. The bucking and strain behavior of flapwise and edgewise are analyzed. Performance of the blade, including buckling and strain under the action of load is investigated, the structural performance advantages are compared with the traditional blade with sharpedge and the blade with flatback. At last, the results of failure experimental are compared with the design value to analyze the error generation causes.

Key words: flatback, blade, static experiment, buckling, strain
