Research on digital transformation of spacecraft development

With the increase of the complexity, cost and development cycle of satellite development, document design intensively under baseline management pattern with PLM system has been difficult to meet the needs of efficient and real-time collaborative design. There are some problems in this pattern such as discrete data sources, discontinuous data flow, and low efficiency of inter-specialty collaborative iteration, which restrict the overall efficiency and level of satellite development. In this paper, a digital development mode based on model penetration is proposed to comprehensively optimize and sort out the collaborative business process of the whole life cycle of spacecraft development, and adopt advanced information technology to form a new and complete R & D capability system. Based on the model, digital collaborative design and simulation verification are carried out to achieve rapid verification and iteration of scheme design, greatly reduce physical tests, and improve the efficiency of R & D design. Through the digital main line, the whole life cycle data will be gathered together and linked to form a complete global and unique truth source, evolutionary traceability chain and comprehensive data view, and promote the integration of the physical form and digital form of the satellite to achieve digital delivery.
