摘要:

飞机研制过程中频繁的构型更改增加了构型管理的困难性和挑战性。为此，提出一种面向频繁构型更改的飞机构型管理方法。首先，构建基于图数据库技术的飞机构型管理框架，将飞机结构以图的形式存储于图数据库中，以便高效直观地管理和追溯构型更改；然后，通过提出面向需求的模块化产品分解结构和阶段式构型标识编码方法，以解决飞机设计与制造阶段中构型频繁更改的管理问题；最后，通过建立面向模块的工程更改传播追溯与有效性标识方法，解决飞机制造阶段中工程频繁更改的管理问题。结果表明：本文所提出的面向频繁构型更改的飞机构型管理方法，能够基于图数据库迅速直观地识别受更改影响的零组件和子系统，有效减少完成更改所需的操作步骤和时间，从而提高构型管理效率。

Abstract:

Frequent configuration changes during aircraft development process increase the difficulty and challenge of configuration management. In this paper, an aircraft configuration management method for frequent configuration changes is proposed. Firstly, a configuration management framework based on graph database technology is constructed, storing aircraft structures in a graph format within the database to facilitate efficient and intuitive management and tracking of configuration changes. Secondly, a demand-oriented modular product breakdown structure and a staged configuration identification coding method are introduced to address the management issues associated with frequent configuration changes during the aircraft design and manufacturing stages. Finally, a module-oriented engineering change propagation tracking and validity identification method is established to manage the frequent engineering changes encountered during the aircraft manufacturing stage. The results demonstrate that the proposed configuration management method for frequent configuration changes enables the rapid and intuitive identification of affected components and subsystems based on the graph database, and significantly reduces the steps and time required to implement changes, thereby enhancing the efficiency of configuration management.
