Qun Zhang Tu, Jian Zhao, Long Qin, Jvying Dai

Abstract

The flow of reverse modeling based on section feature is analyzed, and three algorithms of B-spline curve fitting are studied. Then by adopting the three methods, the sectional curve fitting of the point cloud data is achieved for the stator vane of hydraulic torque converter. Through comparing the errors and curvature of the fitting curves, the effect of curve fitting is analyzed and valuable conclusions are obtained.
