3D geometric model reconstruction of mine axial fan blade using reverse engineering technology
摘要
Abstract
The blade shape of mine axial fan is the crucial influence factor on the aerodynamic performance of mine axial fan. In order to absorb and introduce the advanced design technology, reverse engineering was introduced to reconstruction the 3D geometrical model of mine axial fan blade. Firstly,according to the characteristics of the mine axial fan blade design planning measurement path and the point cloud data of 3D geometrical surfaces of mine axial fan blade were obtained through measuring with a three-Coordinate Measuring Machine (CMM). Secondly,the point cloud data were processed by using UG a software of reverse engineering,including eliminated the abnormal points,the data smoothing and the data simplification of the point cloud. Finally, the non-uniform B-spline curve was introduced to fitting the date points of every cross section. The 3D geometrical model of mine axial fan blade was reconstructed through the method of the curve generating surface. It is of important significance to the direction the optimization design and computational fluid dynamics simulation of mine axial fan.关键词
