Spacecraft assembly oriented three-dimensional structured process design system and method

Abstract

The invention discloses a spacecraft assembly oriented three-dimensional structured process design system and method. The three-dimensional structured process design system comprises a process planning management module, a process digital prototype associated management module, a process compiling module, a process controlled and publishing module. The process planning management module is used for planning process volumes and a process route and establishing a process file structure tree; the process digital prototype associated management module is used for being associated to the process file structure tree and a product structure tree provided by a process digital prototype; the process compiling module is used for allocating materials, tooling, tools and auxiliary resources, compiling process sequences and generating a working procedure route map; the process controlled and publishing module is used for initiating a process approval flow and publishing process files to a field manufacturing execution system. By the spacecraft assembly oriented three-dimensional structured process design system and method, the process digital prototype is taken as a unique data source, close association between the process file structure tree and the product structure tree is realized, and process compiling efficiency is improved by taking typical process statements as templates.

Description

technical field [0001] The invention relates to the field of spacecraft assembly, in particular to a three-dimensional structured process design system and a three-dimensional structured process design method for spacecraft assembly. Background technique [0002] During the "Twelfth Five-Year Plan" period, the development of spacecraft has the characteristics of large quantities, short cycles, and high requirements. It is urgent to "propose the assembly integrated test (AIT) and inspection specification system and implementation of spacecraft based on 3D digital models." Platform planning and scheme to realize the process management of AIT technology and technical status based on the 3D model of the spacecraft." However, the current spacecraft assembly process mainly uses computer-aided process planning (CAPP) and Kanban system to prepare process documents and execution record forms. The means of expressing the design intent of the assembly process documents is very simple,...

Problems solved by technology

However, the current spacecraft assembly process mainly uses Computer Aided Process Planning (CAPP) and the Kanban system to prepare process documents and execution record forms. The means of expressing the design intent of the final assembly process documents is very simple, and it is impossible or inconvenient to convey information such as the product model, product structure and its subsidiary attributes, and the relationship betwee
