基于CATIA的圆滑曲面逆向方法研究

Research on Reverse Method of Smooth Surface Based on CATIA

在CATIA逆向设计过程中,大曲率圆滑过渡曲面是一种常见曲面。对农耕机犁片点云进行逆向,通过改变截面数量,分析逆向曲面和原点云之间的相合度的变化趋势。最后选取了相合度最好的两个逆向曲面,通过曲率分析,确定截面数量对逆向结果曲率有连续性的影响。

In the CATIA reverse design process, large curved surface is very common In this ar- ticle, the farming machine plough point cloud is designed reversely. By changing the section number the change of consistency between the surface and the origin cloud is analyzed finally, two inverse surfaces with the best consistency are selected, and the curvature continuity of the reverse results is analyzed by curvature.
