摘要/Abstract

摘要： 选取大型复合材料风电叶片叶根为研究对象,利用有限元方法,初步研究典型叶根褶皱对风电叶片强度的影响。首先建立含褶皱复合材料平板模型,探讨褶皱位置对构件强度的影响。选取某2 MW叶片,建立含褶皱叶根有限元模型,分析受压状态下,褶皱层数、宽度、高宽比等因素对风电叶片强度的影响。计算结果表明:构件越薄,靠近中间位置褶皱对叶片强度的影响越大;随着褶皱宽度、层数和高宽比的增加,叶片强度有不同程度的降低。研究所得到的初步结论为风电叶片褶皱类缺陷处理提供参考,并为进一步深入研究打下基础。

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.

Key words: wind turbine blade, composite, finite method, waviness, aspect ratio, strength
