整体叶轮自由曲面造型的研究

The Research on the Free-form Surface Modeling of Overall Impeller

介绍了自由曲面造型的基本理论,在UG环境下根据叶片边缘初始数据点,按照相应尺寸要求,做出叶片上下截面,在此基础上采用对截面按照叶片边缘曲线方向进行扫描形成叶片实体的方法。

This article describes the basic theory of free surface modeling. In the UG environment, according to the initial data point of leaf blade edge and size requirements in accordance with the corresponding, the upper and lower section of leaf blade are made, on above basis scaning on the cross section curves is scanned to form a leaf blade entity of the method in accordance with the direction of leaf blade edge.
