Three-dimensional process digital prototyping system and method oriented to spacecraft final assembly and three-dimensional process digital prototyping construction method

Abstract

The invention discloses a three-dimensional process digital prototyping system oriented to spacecraft final assembly and a three-dimensional process digital prototyping construction method. The three-dimensional process digital prototyping system comprises a design data importing module, a process digital prototype management module and a process digital prototype issuing module. The design data importing module is used for receiving and converting design data in an upstream design system. The process digital prototype management module is used for generating a process digital prototype view, reconstructing product structures of the converted design data and filling in structured product attributes. The process digital prototype issuing module is used for issuing a process digital prototype which is approved. According to the three-dimensional process digital prototyping system oriented to the spacecraft final assembly and the three-dimensional process digital prototyping construction method, process data sources are uniform, transmission efficiency of design information of a spacecraft is improved, and a solid foundation is built for achieving the three-dimensional structured final assembly of the spacecraft.

Description

technical field [0001] The invention relates to the field of spacecraft assembly, in particular to a three-dimensional process digital prototype system and a method for constructing a three-dimensional process digital prototype for spacecraft assembly. Background technique [0002] From the development stage of spacecraft, it is generally divided into design stage, manufacturing stage and final assembly stage. Among them, spacecraft final assembly is the last and key part of the spacecraft ground development process. [0003] For spacecraft assembly work, the correct and efficient transfer of design documents and design intent in drawings is not only the primary goal but also the basis for subsequent work. In the traditional mode, assembly technicians need to consult thousands of pages of drawings and technical documents, sort out assembly information from them, and manually input them in computer-aided process planning (CAPP) and kanban systems. Prepare process documents a...

Problems solved by technology

Technicians are unable or inconvenient to convey information such as product model, product structure and its subsidiary attributes according to the requirements of final assembly, and cannot realize the relationship between the three. Facilitate implementation of design changes and product data packages

[0004] After the spacecraft development model has changed from 2D to 3D, the traditional model can no longer meet the new requirements. The spacecraft field urgently needs a unified process data source that can be oriented to the final assembly process design, including product structure, 3D model and structural attributes.
