摘要： 通过总结载人月球探测航天器在关键技术攻关、方案和初样研制阶段中飞行器总体、分系统和单机三个产品层级涉及的基于SysML开发的需求模型、系统设计模型和基于Modelica开发的系统验证模型的数字化工程研制实践经验，提炼形成航天器产品研制过程全周期、全层级、全产品维度的数字模型体系，重点聚焦系统需求分析、系统设计与验证环节，以载人月球探测航天器数字模型为例，分析研究了模型的数字主线中主数据的基本构成，以及数字主线中的主数据在时间维、组织维和产品维的传递规律和航天器产品的技术状态项在数字模型、研试文件、实物产品和数字主线中的映射对应关系，将产品在数字空间的数字模型和物理空间的实物实体的技术状态管控要素进行了有机统一，研究提出基于MBSE的航天器产品数字化研制集成程序，为有效控制航天器数字化研制模式下的技术状态提供技术基础。

Abstract: This study summarizes the MBSE-based digital engineering development practices of manned lunar exploration spacecraft, covering the requirements model developed with SysML, the system design model, and the system verification model developed with Modelica, across three product levels: overall spacecraft, subsystems, and individual components. It distills these practices into a comprehensive digital model system for the entire lifecycle, all levels, and across all product dimensions of spacecraft development. Focusing on system requirements analysis, system design, and verification, the study takes the digital model of manned lunar exploration spacecraft as an example to analyze the fundamental composition of master data in the digital backbone, as well as the transfer processes of master data in the digital backbone across temporal, organizational, and product dimensions. It also examines the mapping correspondence between technical state items of spacecraft products and their representations in digital models, research and test documents, physical products, and the digital backbone. By organically integrating the technical state management elements of products in both the digital and physical domains, the study proposes an integrated MBSE-based digital development process for spacecraft products, providing a technical foundation for effectively controlling the technical state in digital development modes.
