Multiunit cubesat main load-bearing structure

Abstract

The invention discloses a multiunit cubesat main load-bearing structure. A main frame is of a rectangular frame structure and provided with rib plates matched with the shape of the long-edge section of the main frame in the direction of the long edges. End covers are arranged at the two ends of the main frame in the direction of the long edges, and the profile of the end covers is matched with the shape enclosed by the main frame. A middle skeleton is arranged at the positions corresponding to the rib plates in the main frame, and the profile of the middle skeleton is matched with the shape enclosed by the rib plates. Four threaded rods are arranged in the main frame in the direction of the long edges, penetrate through the middle skeleton and are fixed to the end covers at the two ends of the main frame. According to the multiunit cubic-star main load-bearing structure, due to the fact that the main frame is of an integrated structure, parallelism among guide rails can be guaranteed, the main load-bearing structure cannot be clamped by a launcher in the launching process, and successful launch is guaranteed; in the cubesat assembling process, internal PCBs can be assembled with the end covers, the middle skeleton, the threaded rods and nuts firstly, and then the assembled whole body is arranged in the main frame in a sleeving mode; the difficulty of the assembling process is greatly lowered, and the internal layout integrity is improved.

Description

technical field [0001] The invention belongs to the technical field of cubes, in particular to a multi-unit cube star main load-bearing structure. Background technique [0002] In recent years, with the rapid development of technologies such as communications, optoelectronic components, materials, sensors, and applied fluids, the development of CubeSat technology has accelerated significantly, and it has become possible to use CubeSats for 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] At present, there are a variety of cubesat structures, including commercial and self-developed ones, and the design technology of cubesat structures is developing in a flourishing manner. For example:...

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
