基于Geomagic的汽车零件的逆向建模技术及误差检测分析与研究

文章以国产小轿车的配件为原型,针对结构造型复杂以及误差检测复杂的问题,利用逆向工程的方法实现快速精度检测与分析。文章通过天远OKIO扫描仪获取零件的点云数据,运用Geomagic Studio逆向建模软件对点云数据实现NURBS曲面重建。最后利用Geomagic Control X检测软件将逆向建模形成的NURBS曲面与原始设计模型进行3D和2D比较,分析偏差来源,从而为实际生产提供技术依据,通过数据得到修模方案,缩短调模周期。

In this paper,with the domestic automobile parts as the prototype,aiming to solve the problems such as complex structure and complex error detection,this paper uses Geomagic Studio reverse engineering to achieve fast precision detection and analysis.In this paper,the point cloud data of the product is obtained through the TIANYUAN OKIO scanner,and Using Geomagic Studio reverse modeling software,this paper realizes the reconstruction of NURBS surface.Finally,using Geomagic Control X detection software,the reverse NURBS surface is compared with the original design model in 3D and 2D,and the deviation source is analyzed,which provides technical basis for actual design improvement,thereby greatly shortens the design cycle.
