Spatial box type cabin structure

Abstract

The invention relates to the field of spaceflight, is suitable for mounting high-accuracy mechanisms and high-accuracy equipment of a space exploration flight vehicle, and particularly relates to a spatial box type cabin structure. The spatial box type cabin structure comprises a square box body (1), namely a square box piece (1), and four triangular box bodies (2), namely four triangular box pieces (2), wherein the square box piece (1) is positioned in the center of the structure; the triangular box pieces (2) are uniformly distributed on four edges of the square box piece (1), and the four triangular box bodies (2) and the square box piece (1) are in the shape of forming spatial inclined angles; the spatial box type cabin structure adopts the whole configuration that the spatial box type cabin structure is gradually furled from top to bottom through the triangular box pieces (2) and is finally formed into a four-point support structure. The spatial box type cabin structure disclosed by the invention has the beneficial effects of being high in rigidity, high in accuracy, low in weight and the like.

Description

technical field [0001] The invention relates to the aerospace field, is suitable for the installation of high-precision mechanisms and equipment of space exploration aircraft, and particularly relates to a space box type cabin structure. Background technique [0002] According to the lightweight and high-precision design requirements of space vehicles, its mechanism and equipment installation structure must meet the following requirements: have good structural rigidity; meet the high-precision installation requirements of mechanisms and equipment; meet the structural lightweight design requirements. [0003] At present, domestic spacecraft mechanisms and equipment installation structures are mainly divided into two types: space trusses and cones. The main problems in their application and development are as follows: [0004] (1) The assembly form of the space truss is complicated, the structural rigidity is weak, and the adaptability to the later mechanism and equipment inst...

AI Technical Summary

Problems solved by technology

[0004] (1) The assembly form of the space truss is complicated, the structural rigidity is weak, and the adaptability to the later mechanism and equipment installation and adjustment is not strong;

[0005] (2) The installation surface of the cone structure is in the form of a cylinder or a hyperboloid. The installation of the mechanism and equipment needs to be equipped with a large number of adjustment brackets of different structures, which increases the difficulty of ensuring accuracy and the cost of development.
