摘要
Abstract
In this article,large composite wind turbine blade is chosen as research object,and effects of typical root waviness on performance of wind turbine blade are initially studied with the finite element method.First,the plate samples which contain waviness are used to discuss sample's strength influenced by different waviness positions.At last,the finite model of root of 2 MW wind turbine blade is established.When the root blade is pressed,its strength is influenced by many features,such as the number of layer,width and aspect ratio,etc.The results of calculation show that when the sample with waviness is thinner,its strength is lower.With the number of layers,width or aspect ratio increasing,the blade which contains waviness loses its strength apparently.The results of this article provide some reference for dealing with root blades which contain waviness and can be applied for further study.关键词
