基于逆向工程轿车保险杠设计及曲面评价

在对汽车外形的局部改型中,由于逆向设计具有设计精度高、开发周期短及节约成本等优点,逐渐得到厂家的广泛采用。文章根据原型车前后保险杠造型,运用逆向工程原理以及CATIA软件中的模块构建出新的保险杠造型,依据曲线几何连续性条件,利用曲面断面线法、斑马线法及曲面反射性分析法来评价曲面的质量。最终得到更加美观的轿车保险杠外表面造型。该方法大大提高了轿车外表面改型的开发效率。

Bumper Design and Surface Evaluation of a Car Based on Reverse Engineering

In partial modification of auto profile,reverse engineering is used widely because of high design precision,short development cycle and cost saving.According to original bumper modeling of a prototype,using reverse engineering principles and CATIA module create new bumper modeling.Based on the continuous condition of curve geometry,surface section line,zebra line and surface reflection analysis,the surface quality is evaluated.More beautiful outside surface modeling of a car bumper is gained.The method impr...
