摘要
研究了应用非均匀有理Ｂ样条（ＮＵＲＢＳ）描述螺旋进气道外形的方法以及参数化设计的实现途径与关键技术。探讨了螺旋进气道的设计规律及造型的具体方法。实现了根据给定设计参数自动建立柴油机螺旋进气道的三维几何模型的目标。
The method to describe the contour of helical intake ports with NURBS and the key points to realize parametric design are researched. Design rules and modeling method of helical intake ports are explored. Based on given design parameters, the 3 D geometry model of helical intake ports can be automatically built.
