Automatic construction system of digital prototype based on pro/e spacecraft assembly process

Abstract

The invention discloses an automatic construction system and method for a spacecraft general-assembly-technology digital prototype based on Pro / E. The system mainly comprises a three-dimensional design model receiving and inspecting module, a manufacturing information extraction and reconstruction module and a technology model output module. A technology model of a spacecraft is output through inspection and reconstruction. According to the automatic construction system and method, a PVZ-format lightweight model carrying design information can be led out, the browsing viewing problem on a low-configuration host is solved, and according to the basic information and parameter information of the model, querying, real-time viewing and statistics of positioning information and fastening information can also be achieved.

Description

technical field [0001] The invention belongs to the technical field of spacecraft assembly, and in particular relates to a system and method for automatically constructing a digital prototype of a spacecraft assembly process based on Pro / E. Background technique [0002] At present, the product design work of various types of satellites in our country has been widely realized in three dimensions, and various design information is transmitted in the form of three-dimensional models combined with external controlled technical documents. Require. Realizing the rapid construction of a process digital prototype based on a 3D model is the premise and key to subsequent 3D process design and 3D delivery to the factory. However, there are still the following problems in the rapid construction of process digital prototypes: [0003] 1) The overall 3D design data is missing, and some data are still in the form of 2D graphs; [0004] 2) The 3D modeling is not standardized, resulting i...

AI Technical Summary

Problems solved by technology

[0003] 1) The overall 3D design data is missing, and some data are still in the form of 2D graphs;

[0004] 2) The 3D modeling is not standardized, resulting in the failure of the final assembly department to receive it correctly;

[0005] 3) The final assembly information cannot be explicitly expressed, and a large amount of interactive query work is required, which affects work efficiency;

[0006] 4) Part of the key design information is separated from the 3D model, and information cannot be directly extracted from the 3D model
