基于CATIA二次开发的管网关键信息提取方法

Pipeline Network Key Information Extraction Method Based on Secondary Development of CATIA

研究了CATIA图形文件中的管网信息,提出了管线信息、连接信息以及支撑信息自动提取的方法。在此基础上,进行了CATIA二次开发并编制了CATIA管网系统信息自动提取软件,软件作为自行开发飞机管道有限元分析软件的模块,能够实现CATIA管道模型的自动导入,大大降低了有限元建模工作量,提高自行飞机管道系统振动分析、设计、与优化的效率。

This paper studies the pipe network information in the CATIA graphics file,and proposes a method to automatically extract pipeline information,connection information and supporting information.On this basis,CATIA secondary development was carried out and CATIA pipe network system information automatic extraction software was compiled.As a self developed aircraft pipeline finite element analysis software module,the software can realize the automatic import of CATIA pipeline model,greatly reducing the limit Meta modeling workload to increase the efficiency of vibration analysis,design,and optimization of self propelled aircraft piping systems.
