摘　　要：本文在NURBS曲面设计造型理论的基础上,详细给出了YL型烟气轮机动叶片曲面的设计过程。论述了曲面控制顶点以及曲面离散点的计算方法,以及动叶片的三角片划分过程和曲面STL文件输出过程。最后,在兰州石油化工公司机械厂进行实验验证并取得了较好的设计效果。In this paper,the design process based on the theory of NURBS of YL type flue gas turbine blade surface is given in detail. The calculation method of the surface control vertex and the discrete points of the curved surface are discussed,as well as the process of the partition of the blade and the output of the STL file. At last,the experiment was carried out in Lanzhou Petrochemical Company,and the result was proved to have good effect.
