Abstract: Considering the limitation of traditional development mode of spacecraft cable net, a concept of holographic model for the spacecraft cable net and the system for the model are proposed, and the digital definition of complete product including the design information of total factor is realized. Based on the design concept of "first path design and then the cable routing design", a rapid co-design algorithm and related algorithms of spacecraft cable net are systematically proposed. A unified map of cable net channel at the aircraft level is established to effectively enhance the top-level design of the cable net and reduce the problem of unobtrusive consideration and non-optimization of the path of each cable in the parallel design. The integrated cooperation mode of mechanics and electrics and the integrated business process oriented to the development of the whole cycle are constructed. A universal cross-model cross-discipline model library, parameter database, and algorithm and rule base are established to improve the system-level overall design of the spacecraft cable net and the underlying data model, achieving a parallel collaboration between different disciplines. The navigational rapid co-design system of spacecraft cable net is developed to realize rapid three-dimensional routing of complex cable net based on parameter driving and improve design efficiency and efficiency. The method proposed is applied in the manned spacecraft such as the space station, providing an effective method and means for development of complex cable net.
