复杂曲面CAD重构设计中的一种关键技术

分析了复杂曲面CAD重构设计中的基本流程,重点介绍了重构设计中涉及的几个关键技术。首先,介绍一种基于Bezier曲线曲面造型原理的复杂曲面重构方法。该方法用三角网格对将离散点云进行拓扑划分,将一个复杂的零件曲面划分为多个小曲面;然后采用轨迹线生成技术重构复杂曲面中的特征线,采用网格优化技术提高重构效率;最后,采用曲面光顺技术,使重构后的曲面达到应用需求。

Research the Key Technologies of Restructuring Design With CAD for Complex Surface

The paper has analyzed the basic flow in restructuring the complex surface with CAD,and also has studied several key technologies which involve in the restructuring design.One complex surface restructuring method based on the Bezier curve surface modeling principle has been introduced.This method will patition the separated point cloud with triangle grid,which divides the surface of a complex components into many small surfaces;Then the characteristic curve of complex surface is restructured with the axle p...
