摘　　要：针对航天领域数字化转型过程中数字模型体系不健全问题,本文结合欧美航天领域数字化转型发展脉络,梳理了数字模型概念内涵,并从认知、技术、建设与应用四个视角分析了当前航天领域数字模型建设面临的矛盾问题,随后按照数字模型需求、模型分级表达、模型分级设计和模型货架设计的正向设计方法搭建数字模型体系框架,按照指标集、参数集和函数集分级思路提出了仿真模型分级的基本方案,最后从标准化的角度提出了数字模型体系建设的思路举措,为航天领域数字工程模型理论构建提供借鉴,为推进基于模型的航天工程实践奠定基础支撑。In view of the incomplete digital model system in the process of aerospace digital transformation,combined with American and European digital transformation and development,the concept connotation of digital model is sorted out,and the contradictory problems faced by digital model construction in the space field are analyzed from four perspectives of cognition,technology,construction and application.Subsequently,the framework of digital model system is built according to the forward design ideas of digital model demand,model classification expression,model classification design and model shelf design.The basic scheme of simulation model classification is proposed according to the classification ideas of index set,parameter level and function level.Finally,the ideas and measures for digital model system construction are put forward from the perspective of model standardization,providing reference for the construction of digital engineering model theory,and laying a foundation for promoting model-based aerospace engineering practice.
