[0007] The purpose of the present invention is to propose a visual conceptual design method for modular spacecraft in view of the lack of intuitive description of the configuration scheme in the concept design stage of modular spacecraft and the time-consuming technical defects of preliminary analysis of the configuration. Provides a visual conceptual design method that takes modular spacecraft as the design object, realizes the instantiation definition of each component module of the spacecraft, the combination and assembly of modules through the interactive interface, and the rapid performance analysis and evaluation of the spacecraft configuration

Embodiment 1

[0074] The hexahedral modular spacecraft used in this embodiment has six mechanical interfaces, which are evenly distributed on the six surfaces of the module. The characteristics of the orbital service, the hexahedral modular spacecraft is the most widely used spacecraft module in related industries, the basic shape of the modular spacecraft module is as follows figure 2 As shown, the modules in the figure are the basic modules of the modular spacecraft. Compared with the traditional conceptual design method based on multiple commercial software for independent analysis, the visual concept design method of a modular spacecraft proposed in the present invention fully considers the technical characteristics of the modular spacecraft and the design process. Geometric and performance constraints that need to be considered, integrate the original configuration concept design tasks that can only be completed based on multiple software and multiple platforms, realize the instantiat...

Abstract

The invention relates to a visual concept design method of a modular spacecraft, and belongs to the technical field of visual design and simulation. The visual concept design method comprises the steps: 1, conducting attribute definition on composition modules of the modular spacecraft formed by splicing all module units, defined attributes are associated with the modules, and achieving instantiation of a module model; 2, rotating a mouse, dragging the spacecraft to form modules, splicing and combining the modules, integrating the combined modules on a visualization level and a data level so as to support concept design work, and outputting modular spacecraft related information spliced and combined by designers; 3, obtaining relevant information of the modular spacecraft, calling a performance evaluation module to carry out performance analysis including mass, inertia and structure fundamental frequency, and outputting a performance analysis result file; and 4, visually displaying theperformance analysis result file. According to the visual concept design method, the complete process of concept design and preliminary analysis of the modular spacecraft can be realized, and the design efficiency is improved.

Description

technical field [0001] The invention relates to a visual conceptual design method of a modular spacecraft, in particular to a visual conceptual design method of a modular spacecraft based on Unity3D and Nastran analysis software, and belongs to the technical field of visual design and simulation. Background technique [0002] A spacecraft is an aircraft that operates in space according to the laws of celestial mechanics and performs specific tasks such as exploration, development, and utilization of space and celestial bodies. The aircraft system mainly includes a structural system, a power supply system, a thermal control system, and an orbital control system. Among all kinds of spacecraft, artificial satellites are currently the spacecraft with the largest number of launches, the widest range of uses, and the fastest development. Artificial satellites are divided into low-orbit satellites, medium-high orbit satellites, geosynchronous satellites, and geostationary satellite...
