Space truss and spaceflight loading structure for space operation

Abstract

The invention relates to space truss and spaceflight loading structures, in particular to a space truss and spaceflight loading structure for space operation. The space truss and spaceflight loading structure comprises a box body structure and a space truss body. One end of the space truss body is fixedly connected with the bottom of the box body structure. The other end of the space truss body is connected with a tool. A restricted damping layer is arranged on the outer wall of the box body structure. The space truss body comprises long pipe assemblies, short pipes and square connecting blocks, wherein the multiple long pipe assemblies are connected through the square connecting blocks so that a multi-section square or triangular frame can be formed, and every two adjacent squaer connecting blocks are connected through the corresponding short pipe perpendicular to the long pipe assemblies. The space truss and spaceflight loading structure has great damping performance, the optimal damping effect can be achieved by changing the thickness, the material, the laying position and the laying area of the viscoelastic damping layer, and a precise photoelectric instrument is installed in the box body structure for astronauts to perform space operation.

Description

technical field [0001] The invention relates to a space truss and an aerospace load structure, in particular to a space truss and an aerospace load structure for space operations. Background technique [0002] With the development of spacecraft in the direction of large-scale and complex, space trusses have been more and more widely used due to their excellent properties such as easy disassembly, good manufacturability, light weight, and the ability to adjust the structure according to specific needs. , it is also an important part of the International Space Station. The two application aspects of the space truss are to connect relevant optoelectronic devices at the top of the space truss to separate electronic devices to reduce mutual interference, and the other is to use as a supporting structure to support large-scale deployable antennas in space and solar sails on satellites board etc. There are precision optoelectronic instruments inside the aerospace load, which are ...
