摘要: 航空发动机零部件设计中存在许多修改设计和分析的内容,会产生大量的中间版本和各种分析数据,产品数据管理系统只管理用户提交的一些重要版本和数据,大量的中间版本和分析数据被丢失。针对产品数据管理系统的不足,提出了广义版本管理的概念,以设计过程中零件的状态为单元,组织与该状态有关的各种设计和分析数据,组成一个广义版本。分析了零件设计过程中的版本操作,并用图结构描述版本之间的关联关系和版本图的数学表示,建立了广义版本管理模型,有效地实现了面向航空发动机零部件设计过程的版本管理。

关键词: 版本图, 广义版本管理, 产品数据管理

Abstract: There are many modifications and iterative design sub-processes in the design process of aero-engine parts & components, which will produce large numbers of interim versions and correlative data of the parts & components. Only important versions and data were managed by Product Data Management(PDM)system, and most of them were discarded. To deal with the shortcomings of PDM systems, a concept of general version management was proposed and the corresponding general version management model was set up. With this method, the design state worked as the basic unit used to organize various related design data and analysis data so as to form a general version. Version operation in components design process was analyzed and interrelationships among versions were also represented by graphs. Mathematical expression of version graph was studied and general versions management model was also constructed. All of these efforts have effectively implemented version management oriented to the design process of aero-engine.

Key words: version graph, general version management, product data management
