柴油机螺旋进气道计算机三维造型

Computer-aided 3D Modelling of Helical Inlet Manifold of Diesel Engine

根据柴油机螺旋进气道的空间形状特征，运用Belier曲面拟合和ADS技术，在AutoCAD下实现螺旋进气道结构计算机三维造型，为柴油机的螺旋进气道的计算机辅助设计和辅助制造提供了现代方法和手段．

In accordance with the structural features and parameters of the helical inlet manifold, the 3D graph and cartoon are obtained in Auto CAD by using Beizer patch fitting and ADS technique. The results offer a basis for the CAD and CAM of the helica1 inlet manifold.
