摘要
在对风力机叶片进行参数化描述的基础上,基于CATIA二次开发,采用VB语言实现风力机叶片的参数化建模程序。通过研究发现,风力机叶片造型的关键是确定生成叶片蒙皮的导线。实例表明,参数化建模程序运行稳定,执行效率较高,输出的模型可直接用于结构分析,并为叶片气动结构一体化设计打下了基础。
Quick generation of a three-dimensional shape model of blade is one of the most important issues in the process of wind turbine blade design and analysis. The parametric representation of the wind turbine blade configuration was investigated. A Microsoft Visual Basic routine for the parametric geometric modeling of wind turbine blade using API in CATIA was described in this paper. The key issue in wind turbine blade modeling is to determine the guideline of the skin. The example shows that the parametric modeling routine developed here can rapidly generate 3-D shape of wind turbine blade and the model can be directly used in structure analysis and integrated design of aerodynamics and structure.
