System and method for three-dimensionally designing pipelines of spacecrafts

Abstract

The invention relates to a system for three-dimensionally designing pipelines of spacecrafts. The system comprises a basic library module, a channel design module, a pipeline laying module, a pipelineverifying module and a pipeline statistics module. The basic library module is used for establishing and managing model libraries and pipeline parameter libraries which are required for three-dimensionally designing the pipelines; the channel design module is used for establishing all pipeline channels on the spacecrafts and data structures of all the pipeline channels; the pipeline laying moduleis used for automatically generating pipeline three-dimensional models on the pipeline channels, which are established by the channel design module, according to pipeline connection relations; the pipeline verifying module is used for automatically verifying the pipeline three-dimensional models generated by the pipeline laying module; model data can be generated by the pipeline statistics moduleaccording to the pipeline three-dimensional models. The system for three-dimensionally designing the pipelines of the spacecrafts has the advantages that three-dimensional designs for the pipelines of the spacecrafts can be planned in a unified manner, and accordingly the efficiency of the three-dimensional designs for the pipelines of the spacecrafts can be improved.

Description

technical field [0001] The invention relates to the field of three-dimensional digital design, in particular to a three-dimensional design system and method for pipelines of spacecraft. Background technique [0002] The pipeline system is an important part of the spacecraft. It uses gas, liquid and other fluids as the working medium to realize the functions of the operation, control and operation of the related components of the spacecraft. Pipeline design is a key link in the overall design of aerospace, and the rationality of pipeline layout and direction design is an important symbol of the overall design level of spacecraft engineering. [0003] The traditional three-dimensional pipeline design is to use the schematic block diagram provided by the sub-system as the three-dimensional design input, analyze and refine the pipeline installation schematic diagram, determine the pipeline direction, define the conduit components and materials, and sketch the pipeline two-dimens...

AI Technical Summary

Problems solved by technology

After completing the pipeline components and assembly model, path reference points, etc., the designer began to carry out 3D wiring. The wiring needs to consider the implementation of the project, and manually complete the 3D model of the pipeline by setting the starting point, continuation, and stop points. Create, there are many parameters to be set at this stage, the workload is heavy, and there are many iterations, especially in the case of incomplete setting of the path reference point in the early stage, it will cause great trouble to the pipeline direction and cause many inaccuracies in the design. reasonable or even design error

After the 3D design of the pipeline is completed, it is necessary to manually check the correctness of the pipeline polarity and the interference of the 3D model, and mark the basic parameters and BOM (bill of material, bill of materials) information required for the 3D factory, such as pipeline welds. Further increase the workload of pipeline design
