Three-dimensional structured process design system and design method for spacecraft assembly

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. 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 design intentions in process documents is very simple, and it is impossible or inconvenient to convey information such as product model, product structure and its subsidiary attributes, and it is impossible to realize the rel...

Problems solved by technology

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 design intentions in process documents is very simple, and it is impossible or inconvenient to convey information such as product model, product structure and its subsidiary attributes, and it is impossible to realize the relationship between the three, so it is impossible to realize the integration and structuralization of the final assembly process based on the 3D model management, and it is not easy to implement design changes and form product data packages

[0003] In addition, after the spacecraft development model is changed from two-dimensional to three-dimensional, there is no unified process design data source in the field of spacecraft assembly, and the efficiency of process compilation is low, and it is impossible to implement structured control and information collection on site
