| 摘 要： | 建立1.5 MW风力机组塔架的有限元模型,使用有限元分析软件ANSYS对其进行结构动力分析.通过对风力发电机组塔架进行有限元模态分析得到其固有频率和振型,并与使用理论方法对塔架固有频率进行计算的结果相比较,表明塔架与叶轮不会发生共振.因此为塔架安全和进一步的塔架结构动力学分析提供了参考依据.

| Abstract: | The finite element model of the 1.5 MW Wind Turbine Generator Tower is established,and a dynamic structural analysis is made by using ANSYS.Its natural frequency and vibrational mode are obtained and compared with the calculated results about the tower natural frequency given by the theoretic method.Facts show the tower and rotor won't engender resonance,thus providing a basis for tower security and further analysis. |
