基于PDM Enablers的飞行器并行设计文档管理扩展模型研究

并行工程对飞行器设计的重要性不言而喻,产品数据管理(PDM) 是并行工程的支撑技术,文档管理作为PDM系统的基础及核心模块,在飞行器并行设计中起着重要作用.以PDM国际规范"PDM Enablers"为依据,就支持飞行器并行设计的文档管理模型展开研究.在深入研究PDM Enablers的基础上,构建了飞行器并行工程环境体系结构;提出了一种基于PDM Enablers并支持飞行器并行设计的文档管理扩展模型,并着重对其中的文档分类浏览模式、文档状态变迁模型及支持飞行器并行设计的文档信息存储模式进行研究;最后给出了其应用实例,应用表明,所提出的模型可行、有效,能很好地支持飞行器的协同设计.

Research on Extended Document Management Model for PDM Enablers-based Aircraft Concurrent Design

Concurrent engineering is very important to aircraft design. PDM(Product data management) is the supporting technology of concurrent engineering. Document management,which is the foundation and core module of PDM system,plays an important role in aircraft concurrent design. Based on the international standard-PDM Enablers specification,document management model,which is one of the key technologies for aircraft concurrent design,was investigated. Firstly,the architecture for aircraft concurrent engineering environment was built up;then a document management model which is based on PDM Enablers and at the same time supports aircraft concurrent design was put forward,in which document's organization pattern,document's states change model and the document management's information storage model for aircraft concurrent design were researched emphatically;finally an application example was given which shows that the present model is feasible,practical,and can surely surport aircraft concurrent design.
