摘　　要：矿用通风机叶片曲面的加工精度和造型直接关系到今后通风机的使用效率。文章提出了一种基于三次非均匀B样条的方法来完成矿井通风机叶片类曲面的拟合和模型设计方法。通过三次非均匀B样条曲线控制顶点的正算、反算以及节点矢量的计算,借助计算机辅助设计软件Mastercam生成模型,讨论了该方法在今后的通风机叶片类曲面造型上具有广泛的应用前景。Mine ventilator blade curved surface machining precision and shape related to the ventilator efficiency. This paper presents a method based on the three non uniform B spline method to complete mine ventilator blade curved surface fitting and model design method. Through three times of non uniform B spline curve control points are considered, inverse and the node vector computing, computer aided design software Mastercam to build the model, discusses the method in the future of the fan blade curved surface modeling and has broad application prospect.
