摘　　要：结合RE技术对调节阀阀瓣型线进行逆向拟合设计。通过HandyScan3D拍照测量机对实物的数据采集,得到了阀瓣的点云数据,并根据点云提取所需的曲线特征数据,利用正交函数作最小二乘拟合,给出了阀瓣曲线反求拟合的技术路线。The reverse design of the valve core regulating curve part is performed in combination with RE technologies.The collection of valve data in kind by the MAXSCAN photograph measuring engine is to get the valve core point cloud data and obtain the necessary curve characteristic data by the characteristics of clouds data collection.Using orthogonal function as the least-square fitting,has given the curve fitting technique route for the reverse valve core.
