风力机叶片的有限元建模

The Finite Element Analysis of Wind Turbine Blade

以750kW中等长度水平轴风力机叶片为例,应用ANSYS软件,通过GUI操作界面实现复合材料风力机叶片的有限元建模。使实体模型可直接运用于力学性能分析,而无需再在CAD软件与有限元软件间相互转换。同时由于ANSYS软件对于复合材料分析的良好支持,使所建模型能更为真实的反映其结构性能,从而更好地为风力发电机的设计、分析服务。

This paper gives an example of finite element modeling of composite wind turbine blade in ANSYS by means of the medium - length blade of 750kW horizontal axis wind turbine. This model can be directly used in mechanics analysis without mutual conversion between CAD software and finite element program. An accurate composite finite element model has been achieved in ANSYS due to its good quality in composite elements analysis. The model reflects the real condition inside a composite structure and can be used in wind turbine design and analysis.
