基于NX的汽车车身A级曲面设计与质量分析

摘要

The car body class A surface design workflow is introduced in the paper. A car front bumper surface design is taken for ex-ample , the key techniques and methods of car body class A surface design and analysis are presented after discussion on these crit-ical procedures of class A surface design and according to the surface geometry characteristics division, main and auxiliary surface creation and surface quality analysis.%介绍了车身A级曲面设计的一般流程。以某汽车前保险杠盖板A级曲面实现为例，通过车身曲面几何特征划分，主、辅曲面构建及曲面品质检测等设计过程，探讨了实现汽车A级曲面建模和曲面质量检测的关键技术和方法。
