Three-unit cube satellite main load bearing structure

Abstract

The invention discloses a three-unit cube satellite main load bearing structure which is composed of a main frame, end covers, middle frameworks, threaded rods, end nuts and a middle support. The mainframe is of a cubic frame structure, the two end covers are arranged at the two ends of the main frame in the long side direction, the two middle frameworks are arranged in the middle positions of the main frame in parallel in a spaced mode, the middle support is arranged between the middle frameworks in parallel, and the four threaded rods are arranged in the main frame, penetrate through the middle frameworks and the middle support and are fixed to the end covers at the two ends of the main frame. The assembling difficulty of a cube satellite is lowered, and the integrality of an internal layout is improved. Due to the fact that the main frame is of an integrated structure, the parallelism between guide rails can be guaranteed, the structure and a satellite and rocket separation deviceare not locked in the launching process, and the successful launch is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of cube satellites, in particular to a three-unit cube satellite main load-bearing structure. Background technique [0002] In recent years, with the rapid development of technologies such as communications, optoelectronic components, materials, sensors, and MEMS devices, the development of CubeSat technology has accelerated significantly, and it has become possible to use CubeSats for space remote measurement and testing. The low cost has prompted the emergence of cubesat development programs around the world. More and more of them come from the government, enterprises, especially academic institutions with strong scientific research capabilities. The United States and Europe have launched a large number of cubesats. [0003] CubeSat (referred to as CubeSat) belongs to the category of micro-nano satellites, and its development is extremely rapid, and it has been standardized, modularized, and commercializ...

AI Technical Summary

Problems solved by technology

The contact between the Cubestar and the POD is the sliding fit between the four guide rails and the parallel groove-shaped guide rails inside the POD. Therefore, once the parallelism between the four guide rails of the CubeStar cannot be guaranteed, it is easy to get stuck. It directly leads to the failure of the cube star to be pushed into space

This means that the launch fails and all work is meaningless
