摘　　要：叶片是风力发电机组有效捕获风能的关键部件,其结构设计直接影响风能的转换效率,是风能利用的重要一环。运用三维建模软件建立了叶片三维有限元模型,对模型进行静态结构分析以及模态分析,进而得到叶片应力应变和振型图。仿真结果表明,叶片最大位移发生在叶尖处,同时应力主要集中于叶根与叶尖部,在工作时要尽量避开大频率,避免共振,同时运用有限元分析软件可以得到叶片参数对叶片性能的影响,从而可以对叶片结构提出相应的设计改进意见。As blades are key components for wind turbines to effectively capture wind energy,their structural design directly af-fects the conversion efficiency of wind energy,making them an important part of wind energy utilization.The 3D finite element model of blades is established by using 3D modeling software,and then static structural analysis and modal analysis are carried out on the mod-el to obtain the stress-strain and vibration mode diagrams of the blades.The simulation results show that the maximum displacement of the blade occurs at the blade tip,and the stress is mainly concentrated at the blade root and tip.During operation,it is necessary to avoid high frequencies and resonance as much as possible.At the same time,the influence of blade parameters on blade performance can be obtained by using finite element analysis software,which can provide corresponding design improvement suggestions for the blade structure.
