Abstract

The X bill of material (XBOM) of a missile and rocket product is a comprehensive and basic support document produced by a multi-stakeholder that considers structural composition, data information and interactional processes in different life stages. The XBOM data management of missile and rocket products coordinates the data organization and control in the whole life cycle, eliminates the interactional disconnection and one-way transmission between related parties, business and data in different life stages and provides effective data source support for the full digital model supply. To meet the requirements of organic integration and multi-party collaboration, this paper proposes the XBOM data management method based on digital thread. Firstly, the digital thread framework is analyzed, and the XBOM data management architecture based on the digital thread is proposed and established. Secondly, guided by the hierarchy of "data-interaction-modeling-application", the XBOM data management method for the missile and rocket product are developed, including data organization, data relational analysis, data modeling and data application. Finally, the structural system of a certain model of carrier rocket is studied, and the XBOM data management system based on digital thread is developed and its application is validated.

摘要

弹箭产品的多视图物料清单XBOM(X bill of material)是多利益攸关方从不同寿命阶段的结构组成、数据信息以及交互流程等角度对弹箭产品的全方位基础支持文件。对弹箭产品XBOM数据进行管理，统筹管控全寿命周期内的数据，可消除不同寿命阶段相关方、业务及数据间的交互脱节及单向传递，为弹箭产品实现全数字模型供应提供有效数据源支持。为满足面向弹箭产品XBOM数据的有机集成及多方协同需求，提出了基于数字主线的弹箭产品XBOM数据管理体系和方法。通过剖析数字主线框架，提出并建立了基于数字主线的弹箭产品XBOM数据管理体系。以“数据-交互-建模-应用”的体系层次为指导，提出了基于数字主线的弹箭产品XBOM数据管理方法，包含数据组织、数据关联关系分析、数据建模及数据应用。以某型运载火箭结构系统为对象，开发基于数字主线的弹箭产品XBOM数据管理体系并进行了应用验证。文中所提出体系和方法为实现弹箭产品XBOM数据管控、集成及共享提供具体指导，有利于促进我国弹箭产品全寿命周期数据管理系统的发展。
