    摘要:

    修復(fù)車身覆蓋件CAD數(shù)據(jù)是有限元分析前處理中的重要步驟，針對(duì)車身覆蓋件CAD模型中曲面縫隙問題，采用NURBS技術(shù)對(duì)曲面縫合加以研究，通過管柱算法快速判定匹配邊界，以基于特征的曲線合并方法完成曲面縫合，并開發(fā)出曲面縫合算法模塊。通過對(duì)汽車翼子板零件的縫合驗(yàn)證了算法的有效性。

    Abstract:

    Repairing of panel CAD geometric model is an important pre-processing step of the finite element analysis, and widely used in the computer-aided geometric design field. This paper focused on the surface healing method of panel CAD model, which was proposed and analyzed by NURBS technology. Firstly, matching-curves border was determined fast through the pipeline method, the surfaces were stitched by the matching-curves method with characteristics. On the basis of the algorithm, a surface stitching program module was developed. The validity of algorithm was verified by healing automobile front fender parts.
