风力发电机机舱底座有限元分析

Finite Element Analysis on Wind Generator Cabin Base

通过SolidWorks三维绘图软件建立实体模型,导入ANSYS Workbench中进行静力学分析与模态分析,设计了一种机舱底座。结果表明,机舱底座满足结构强度要求,满足使用要求。在模态分析当中,得出底座的前三阶振型和前五阶固有频率与叶轮旋转频率不存在共振现象。

A solid model has been established by SolidWorks 3D drawing software and further statics analysis and modal analysis of the model have been conducted in ANSYS Workbench to finally design a wind generator cabin base.The results showed the cabin base achieved structure strength requirements in practice.Modal analysis concluded that resonance phenomenon didn’t occur between vibration shapes of the former three phases&natural frequencies of the former five phases of the base and blade wheel rotational frequency.
