摘要
详细阐述了B样条曲线理论知识,并以三次非均匀B样条曲线作为截面曲线进行拟合,完成了矿用通风机叶片曲面的设计。叙述了计算机辅助设计造型的开发流程和误差的评估办法,并以实图展现了所设计的通风机叶片曲面。
This paper elaborates the b-spline curve theory knowledge, and fits the section curve with third non-uniform b-spline curve, and finishs the design of mine fan blade surface in three parts. Finally this paper describes the development process of computer aided design modeling and the measure of error evaluation, and show the show the design of the fan blade surface by drawing.
