3D Realistic Digital Prototyping System and Construction Method for Spacecraft Assembly

Abstract

The invention discloses a three-dimensional practical digital prototype system and a three-dimensional practical digital prototype construction method for spacecraft assembly. The 3D digital prototype system includes an interface module for obtaining the execution records of the on-site manufacturing execution system; an execution record management module for analyzing the types of execution records according to the execution records of the on-site manufacturing execution system, and Record the corresponding three-dimensional structured process files and three-dimensional process digital prototype, generate the practical process tree and its associated processes, the practical digital prototype tree and its associated process digital prototype, so as to generate the practical digital prototype. The three-dimensional actual digital prototype system and the three-dimensional actual digital prototype construction method for spacecraft assembly of the present invention realize the organic unity of design data, process data and production data, and form a structured and visualized electronic data package for the entire satellite assembly.

Description

technical field [0001] The invention relates to the field of spacecraft assembly, in particular to a three-dimensional actual digital prototype system and a three-dimensional actual digital prototype construction method for spacecraft assembly. Background technique [0002] The technical state control of spacecraft assembly is mainly realized through the collection, statistics and analysis of spacecraft technical data, which generally includes design data, process data and on-site production data. In the traditional working mode, the design data is generally two-dimensional drawings and technical documents, the process data is the text information generated in the computer-aided process planning system (Computeraided process planning, referred to as CAPP), and the on-site production data refers to the information generated during the production process. The data. [0003] In the traditional working mode, the correlation of design data, process data and on-site production da...

Problems solved by technology

[0003] In the traditional working mode, the correlation of design data, process data and on-site production data is realized manually, or simply structured. In the situation of frequent changes in technical status, it is more difficult for craftsmen to achieve technical status Controlled "Zero Defects"

[0004] At the same time, the current spacecraft assembly process design tools cannot convey information such as product models, product structures and their subsidiary attributes, and cannot realize the relationship between the three, so it is impossible to realize the integrated and structured management of the assembly process based on the 3D model. It is also not easy to carry out design changes and form an entire star product data package
