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。
The theory of B-spline curve is expounded in detail, and the cubic non-uniform B-spline curve is used as the fitting curve to complete the design of the surface of the mining ventilator’s blade. Describes the computer aided design modeling of the development process and error assessment methods, and to illustrate the design of the fan blade surface.
