A system for automatic construction of 3D model of rocket tank structure

Abstract

The invention discloses a system for automatically building a three-dimensional model of a rocket tank structure, which includes a database, a parameter input module, a parameter storage module, a model scheduling module, a three-dimensional model generation module, and a three-dimensional model assembly module; The 3D model of the structural part is required; the parameter input module sends the design parameters input by the user to the parameter storage module for storage; the parameter storage module caches the user design parameters; Perform traversal retrieval in the database and query the model matching the request; the 3D model generation module sends the model call request to the model scheduling module and calls the corresponding 3D model data in the database; the 3D model assembly module assembles the required structural parts and completes Construction of 3D model of storage tank. The invention improves product design efficiency and product design quality, and shortens product development cycle.

Description

technical field [0001] The invention belongs to the three-dimensional rapid design technology of a launch vehicle, and relates to an automatic construction system for a three-dimensional model of a rocket tank structure. Background technique [0002] At present, when designers use 3D model design software to design the structure type of rocket body tanks, there are a lot of similarities in the process from the overall skeleton model design of the tank, the layout of the tank bottom flange, the reference transfer to the detailed design of the structure. repeating work. At the component level, some components such as wall plates, short shell plates, melon petals, end frames, flanges, anti-sway plates, clamps, etc. have a large number of types and similar structures. The design process of these components It is tedious and repetitive work. Designers need to spend a lot of time and energy in the complex operation process of the software, which leads to low design work efficien...

Problems solved by technology

At the component level, some components such as wall panels, short shell plates, melon petals, end frames, flanges, anti-sway plates, clamps, etc. have a large number of types and similar structures. The design process of these components tedious, repetitive work

Designers need to spend a lot of time and energy in the complex operation process of the software, resulting in low design work efficiency and directly affecting the product design cycle

[0003] In addition, in the design process using the standard modules of the 3D model design software, due to the differences in the design levels of different designers, the quality of the design models is uneven, and the design norms are not high, which affects the overall modification of the product digital prototype model and the digital model. equipment, which indirectly affects the correctness of product design
