基于主模型的协同设计软件架构技术研究

运载火箭总体方案论证过程中,由于涉及专业多、专业间迭代交互频繁、设计方案多变等特点,容易造成多专业协同设计时版本与技术状态的不统一,需要研究针对运载火箭产品的通用建模方法,并开发相应的软件系统；基于统一数据源的协同设计理念,结合运载火箭总体设计与数据模型特点,通过定义基础信息模型、概念模型、参数模型、外部定义模型4种数据模型,提出了针对运载火箭产品的通用主模型构建方法；将此通用建模方法软件化,搭建了基于主模型的协同设计软件系统整体架构；此架构包含主模型管理系统、主模型建模工具及应用客户端三部分,实现了多专业协同设计过程中数据与版本的统一管理、技术状态一致性分析、谱系追踪、数据展示与应用等功能；该主模型建模工具与客户端软件系统的实现,为运载火箭的总体协同设计提供了工具支撑。

Research on Software Architecture of Collaborative Design Based on Master Model

In process of launch vehicle overall project conceptual design, due to the characteristics such as multidisciplinary collaboration, frequent iteration and cross disciplinary interaction, and changeable design, the inconsistency between version and technical states among always happen. A general modeling method for launch vehicle is necessary and corresponding software system is desired. Based on the concept of uniform data source collaborative design, combined with the characteristic of launch vehicle system design and data model, through the definition of four kinds of model which included base information model, concept model, parameter model and external definition model, a modeling method of launch vehicle general master model construction is proposed. Further, by developing software to implement the modeling method, a general collaborative software system architecture based on master model is constructed, which included master model management system, master model modeling tool and the application client. It could achieve the version management, the technology consistency analysis, the data lineage tracing and data showing and application, etc. The implementation of modeling tool for master model and the client software system provides tool support for launch vehicle system design.
