UG软件在汽车车身CAD建模中的使用

Application of UG Software in Auto Body CAD Modeling

汽车工业的发展很大程度上反应了一个国家的经济状况,随着汽车行业的竞争加剧,汽车企业将创新重点放在了汽车设计技术上。计算机辅助设计(CAD)技术是汽车设计方面必定广泛采用的技术,此技术能够缩短汽车开发周期、提升产品质量并降低生产成本。选择奥迪R8车身造型为研究对象分析汽车车身建模的过程,介绍了UG软件以及CAD技术的概念与优势,应用UG软件具有的自由曲线曲面造型功能,将奥迪R8汽车车身主要轮廓线勾画出来,经UG软件的使用,最终得到汽车车身模型。此方法也适用于其他品牌汽车车身建模。

The development of automobile industry reflects the economic situation of a country to a great extent.With the increasing competin of automobile industry,automobile enterprises focus on automobile design technology.Computer aided design(CAD)technology is widely used in automobile design,which can shorten the automobile development cycle,improve product quality and reduce production costs.This paper selects Audi R8 body modeling as the research object,analyzes the process of car body modeling,introduces the concept and advantages of UG software and CAD technology,and uses the free-form curve and surface modeling function of UG software to sketch out the main contour line of Audi R8 body,and finally obtains the car body model through the use of UG software.This method can also be applied to other brands of car body modeling.
