基于CATIA V5的汽轮机叶片的反求设计

摘要

Introduced the inverse technique and the design method of CATIA reverse engineering.It finished the reverse design of the turbine blade by gathering the turbine blade point clouds, pre-processing the data and modeling threedimensional entity.And it discussed the method of data processing of the point clouds, the reconstruction of the geometry and the techniques and methods used in the reverse design process.%介绍了反求技术以及CATIA逆向工程的设计方法,通过对汽轮机叶片的点云采集、预处理以及三维实体建模,实现了叶片的反求设计,并讨论了反求设计过程中点云处理、几何重构以及曲面设计过程中的技巧和方法.
