基于MBSE的载人航天器研制应用研究与实践OA

From the perspective of systems engineering,the application and practice of Model-Based Systems Engineering(MBSE)in the development of large-scale complex manned spacecraft is investigated.Based on the overall planning of the digital model system and combined with the systems engineering development workflow including requirement analysis,functional design and verification as well as product design and verification,six categories of digital models are defined.The supporting relationship between various digital models and application objectives,as well as the inherent connection between the digital model system and spacecraft engineering development are analyzed in this paper.The applications of digital models in key development stages such as requirement analysis,system behavior design,architecture design,reliability and safety design,and multidisciplinary system simulation verification are elaborated in detail.A digital development management mode is summarized from the perspectives of organizational structure,standard specifications,technical configuration control and quality assurance.The comprehensive applica-tion effectiveness of MBSE in manned spacecraft development is assessed from three dimensions:design empowerment,test verification and engineering standardization construction.The pro-posed MBSE development paradigm can provide important references for the digital systems engi-neering of similar complex spacecraft.
