摘要
根据反求工程的实施过程,得到基于实物的叶轮反求建模的思路是将点云拟合成曲线再形成体,采用B样条插值实现了叶片表面点云的拟合,给出基于B样条插值的叶轮反求建模算法,进而利用API函数在SolidWorks里实现了三维叶片体及叶轮实体。
Based on impeller＇ s practicality, it analyses math theory base on the fitting of curves B-Spline, and develops impeUer＇s reverse arithmetic based on it.and achieves its 3D model by the API function of SolidWorks.
