| 摘 要： | 动态性能对叶片疲劳和可靠性有很大影响.为了减少动态性能的影响,振动研究常用于避免共振.目前,对叶片振动研究的模型因为没有全面考虑叶片的材料和结构的复杂性而存在不足,本文在abaqus环境下,建立复合材料叶片,划分网格,施加约束,采用有限元方法进行模态分析,得到六阶固有振动频率、振型等参数值.同时讨论复合材料叶片动力刚化...

| Abstract: | Dynamic stress of wind turbine blade has great influence on its reliability and fatigue life.In order to decrease the magnitude of dynamic stress,frequency modulation method is often used to avoid resonance.At present many models of calculating inherent vibration frequency of blade don't consider the randomness of many parameters(such as loading parameters,geometric parameters,material parameters) in practical operation.So this paper creates a composite material model for a wind turbine blade.Blade model is... |
