Description

technical field [0001] The invention relates to the field of spacecraft final assembly, in particular to a three-dimensional model-based spacecraft final assembly information changing system and method. Background technique [0002] In the traditional working mode, the spacecraft final assembly design data is generally two-dimensional drawings and technical documents, and the process data is text information generated in a computer-aided process planning system (Computer Aided Process Planning, referred to as CAPP). The traditional change data are all in two-dimensional format, such as design change order, technical notice and on-site technical problem handling order, etc. These change data are checked, signed and controlled by the technicians, and are used as the basis for the implementation of the change of the final assembly state. [0003] It can be seen from the above analysis that since the design change data, process files, etc. are all two-dimensional data, the relat...

Problems solved by technology

[0003] Through the above analysis, it can be seen that because the design change data and process documents are all two-dimensional data, the relationship between design data, process data and on-site production data cannot be established, so design changes, process changes, and on-site changes are all done manually way to complete

In the process of spacecraft development, the technical status changes frequently, and it is even more difficult for craftsmen to achieve "zero defect" technical status control. At the same time, frequent communication with design, scheduling, operation and inspection personnel is required, which reduces work efficiency.

[0004] In addition, due to the limitation of data sources in the traditional mode, operation simulation cannot be carried out before the design change is implemented, and frequent discussions and confirmations by all parties are required before the change operation can be carried out, and the operator's experience needs to be used for judgment during the period
