面向CAE的汽车覆盖件模面设计中零件边界光顺技术

Contour smooth technique in CAE-oriented die-face design for automotive panel

探讨了面向CAE的汽车覆盖件模面设计中光顺零件边界的几个关键技术,给出了零件边界需要光顺区域的判断依据和NURBS光顺曲线的生成方法和流程,开发了相应的参数化设计模块。通过对某汽车前翼子板等实际覆盖件边界的光顺验证了算法的可行性。

Key techniques about how to smooth the contour of automotive panel were discussed. The method for judging the areas which need to be smoothed and the procedure used for generating the NURBS smooth curve of the stamping part contour were presented. The relevant function modules for parametric design were developed. The feasibility of techniques was proved by creating the smooth surface on the contour of practical parts.
