贯流式水轮机转轮叶片的三维造型

摘要

The blade is an important part of the wheel, it is difficult to directly put the two-dimensional CAD into Pro / E. Based on the three-dimensional coordinates, the curve of the blade section generated multiple IBL file by Matlab that closed the gap of section curve at the adjacent section curve coordinates. In order to read into the data file import Pro / E, each curve is generated in accordance with dividing into two halves on the back surface. Furthermore, blade of the entities relied on text editor for repairing. Finally, three-dimensional modeling will be completed.%叶片是转轮的重要组成部分,且叶片上冠曲线为空间曲线,难以通过二维CAD直接导入到Pro/E,因此,以水轮机转轮叶片的三维坐标为基础,利用Matlab生成多个ibl文件的叶片截面曲线,对不闭合截面曲线缺口处,以相邻截面曲线的坐标进行缝合,然后以读入数据文件的方法依次导入到Pro/E,将各个曲线按照正、背面分成两半面的方法生成曲面,最后叶片实体以编辑文件的方法进行修型,最终实现叶片的三维造型.
