Development of Automated Design Auxiliary System for Auto Panel Trimming Block Based on CATIA

目的基于CATIA平台,开发汽车覆盖件修边镶块自动化设计辅助系统。方法对修边镶块的设计流程进行分析,先采用滚圆算法对修边工艺线进行光顺前处理,再将修边工艺线进行类型划分,以矢量计算的方式获取轮廓方向,开发了基于无向加权图的最小轮廓识别算法,以串并行结合的建模方案对镶块进行自动化建模。结果系统实现了修边镶块的自动化设计,并可同步更新。结论系统集成修边镶块的设计制作流程,显著提高了设计效率,缩短了设计周期。

The paper aims to develop an auxiliary system for the automatic design of automotive panel trimming inserts based on the CATIA platform.The design process of trimming inserts was analyzed.First,the spheronization algorithm was used to smooth the trimming process line,and then the trimming process line was divided based on types,and the outline direc-tion was obtained by vector calculation.The minimum contour recognition algorithm of the weighted graph uses the serial and parallel modeling scheme to automate the modeling of the inserts.The system has realized the automatic design of trimming in-serts and can be updated simultaneously.The design and production process of system integrated trimming inserts significantly improves the design efficiency and shortens the design cycle.
