飞机管路流动性能仿真几何信息自动提取方法

Automatic Geometry Extracting Method on Aircraft Pipeline Flow Simulation

针对飞机管路零件中的导管与接头实体几何拓扑关系复杂,流动性能仿真几何信息自动提取方法不通用等现状,应用CAA技术在CATIA中实现了一种基于属性面边图的飞机管路流动性能仿真几何信息自动提取方法。实践证明,该方法通用有效,满足工程需求。

Solid geometry and topology of pipe and joint in the aircraft pipeline part is so complicated that now automatic geometry extracting method of pipeline flow simulation is not a general one. Considering the current conditions, an automatic geometry extracting method on aircraft pipeline flow simulation based on face and edge attribute graph in the CATIA was achieved and it was implemented through CAA. Engineering practice shows that this method is a general and effective one, and can meet the engineering requirement.
