摘　　要：空间站是我国载人航天领域当前最为复杂的航天器型号,其研制过程涉及专业面广、技术难度大、安全性、可靠性和寿命要求高,由此对系统研制和在轨应用带来了新的挑战。遵循基于模型的系统工程思想,文章提出了数字空间站的初步概念,阐述了数字空间站的建设思路和技术特点,详细论述了数字空间站的技术方案,包括主要功能、总体架构、多学科集成仿真模型库等,及其应用情况。通过数字空间站的应用,有力提升了空间站系统总体层面的综合仿真验证能力。目前数字空间站已应用于空间站在轨运行阶段,后续将不断进行数字化创新,为空间站后续运营任务提供有力保障。As so far, the China Space Station is the most complex manned spacecraft of China Manned Space Program, which is huge system engineering with complex system composition, multidisciplinary collaboration, high safety, great technical difficulty, high reliability and long life span requirements. Thus there are new challenges for the system development and application. According to the thinking of model-based system engineering, a concept of digital space station is proposed in this paper. Then its construction ideas and technical features are described, the technical solution, including the function, the framework and multidisciplinary integrated simulation model library, and its application are also discussed in details. The capability of comprehensive simulation verification and validation at the space station system level is improved through practical application of digital space station. At present, the digital space station is used at on-orbit phase of space station, and in future it will provide a strong guarantee for the following mission of space station operation by continuous digital innovation.
