飞机数字化装配数据集成管理研究

Data Integration Management of Digital Assembly for Aircraft

为了适应现代飞机制造业数字化管理的需要,提高装配数据的共享度和集成度,本文论述了飞机数字化装配数据集成的内涵,通过分析飞机数字化装配业务流程,明确了装配数据在信息化管理软件PDM、CAPP、ERP、MES之间的数据交互过程,以网络和虚拟数据库技术为支撑,建立了以PDM为核心的系统集成框架,并建立了集成产品、工艺、资源和检验的统一装配数据模型,最后提出了一种PDM与CAD、PDM与CAPP、PDM与ERP/MES系统集成模式,并利用XML文件作为中间转化格式,实现系统之间的信息交换与共享。

To meet the current needs of digital management in aircraft industry and enhance the assembly data sharing and integrating, the connotation of the data integration management is discussed, and the information interaction among the PDM, CAD, CAPP, ERP/MES is confirmed by analyzing the work flow of the aircraft assembly in this paper. The system integration frame is established by the support of network and virtual database, in which the center is PDM platform. And the proposed uniform data model can integrate product, process, resource and inspection data for different systems. Finally the integration pattern of PDM and CAD, PDM and CAPP, PDM and ERP/MES is identified using XML files that are represented as the neutral file of the assembly data, by which the exchange and sharing of the data can be realized.
