Embodiment Construction
[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation examples.
[0030] The assembly of satellite cables is a complicated and meticulous work, which needs to comprehensively consider the cable connection relationship between equipment, cable contact table, cable identification, cable direction, electrical connector, etc., in order to accurately describe the satellite 3D cable model for assembly method, the present invention introduces the concept of MBD data sets and the way of 3D model delivery to the factory. First, the digital 3D cable is fully described, and then, the product structure tree related to assembly and its corresponding digital assembly view are extracted. Then, the adopted The general assembly information represented by the MBD data set is extracted to form a general assembly model description file, which is distributed to the factory together with the digital general assembly v...

The invention discloses a manufacturing method of a digital cable general-assembly model for satellite cabins. The method comprises the following steps: (1) setting up a production structure tree of satellite cabins and a three-dimensional digital cable model corresponding to the production structure tree of satellite cabins; (2) simplifying and extracting the three-dimensional digital cable model as well as assembling a related product structure tree and a digital general-assembly view thereof; (3) offering general-assembly information to a to-be-installed electric connector at the cable terminal in the view; (4) extracting product structure information and general-assembly information for collection in order to form a description file for a general-assembly model; (5) sending the description file for the general-assembly model and the digital general-assembly view to a three-dimensional process system on the site of general assembly, adding auxiliary tools and process information required by assembly, generating the digital cable general-assembly model and a matched detailed list used for guiding actual assembly of cables. The whole process of the manufacturing method is digital, which realizes digital cable development and rapid installation. In this sense, assembling efficiency is greatly increased.
Description
technical field [0001] The invention relates to a method for making a digital assembly cable model of a satellite cabin section, which is used to guide the actual assembly of cables and belongs to the technical field of satellite cable development. Background technique [0002] The basis of satellite cable installation The traditional method is to draw the approximate direction of the cable in multiple two-dimensional satellite isometric drawings, and use different line types (solid line, dotted line, thickness) according to power cables, signal cables, and pyrotechnic cables To draw, bundles of cables go together indistinguishable. The equipment supports to be used are attached in the form of attached two-dimensional drawings. And use the partial view to indicate the way of partial installation. The information used in the final assembly is drawn out in the form of lead-out lines and schedules. In the traditional two-dimensional formwork sampling production, the factory ...
