Finite Element Analysis for the Vibration Characteristics of Wind Turbine Blade

  • 摘要: 风力发电机叶片是一种细长的弹性体结构,运行时容易发生振动和变形,严重影响风力发电机的平稳运行。运用有限元数值方法研究风力机叶片的振动特性,利用模态分析法研究了叶片的静频和动频特性,获得了叶片的前6阶振动频率和相应振型。表明挥舞和摆阵是叶片的主要振动形式;在一定来流风速和转速作用下对叶片进行有预应力的振动特性分析,获得了风速与转速的变化对叶片振动频率的影响规律。利用谐响应分析法研究在最大风压与转速作用下叶片的振动特性,获得了最大受迫载荷作用下,叶片位移频率响应的变化规律。
