螺旋进气道的三维造型设计研究

Research on 3-D Modeling Design of Helical Intake Ports

开展了发动机螺旋进气道的三维造型设计的研究。应用非均匀有理B样条 (NURBS)描述气道外形的方法以及仿形设计与概念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 。

The 3-D modeling design of engine helical intake port has been studied. The method to describe contour of helical intake ports with NURBS and the key technique to realize profile modeling and concept design have been researched. The design rule and modeling method for helical intake port have been explored. The purpose to automatically establish the 3-D geometry model of helical intake ports based on the given design parameters has been realized.
