Repair geometric model by the healing method

Abstract

Repairing the 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. Through the pipeline method determines the matching-curves border fast firstly, make the curves discrete points sets and on the basis of the characteristics of the matching-curves method, the surfaces were stitched. 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. © 2012 Springer-Verlag.
