风力发电机复合材料叶片结构特性分析

摘要

At present, with the increasing requirement of wind turbine blade performance, some new composite materials that are applied in wind turbine blade manufacture has been comprehensively focused and researched. Aiming at the difficulty to calculate structure properties of composite materials blade because of new composite materials and the complex structure, based on the FAST software, a blade model, which divides a 1.5 MW wind turbine blade into several sections, and describes shape, internal structure and material of each section by use of the finite element principle, is established to analyze and research the structure properties of composite materials wind turbine blade.%随着对风力发电机叶片性能要求的提高,新型复合材料在风力发电机叶片制造中的应用得到了广泛的关注与研究.由于新型复合材料及风力发电机叶片结构具有一定的复杂性,因此风力发电机复合材料叶片的结构特性很难计算.文章基于FAST软件,以1.5 MW风力发电机复合材料叶片为例,运用有限元原理将叶片分成若干叶素面,通过描述各个截面的几何形状、内部结构以及材料等来建立叶片模型,对风力发电机复合材料叶片的结构特性进行了分析研究.
