Six-unit cubesat main force bearing structure

Abstract

The invention discloses a six-unit cubesat main force bearing structure. The six-unit cubesat main force bearing structure is formed by means of the method that two three-unit cubesat main frames cooperate with each other through a connecting frame. The main frames are each of a cuboid frame structure, end covers are arranged at the two ends of each main frame in the direction of the long edge, and middle frameworks are arranged in the middles of the main frames. Four screws are arranged in each main frame and penetrate through the corresponding middle framework to be fixed to the end covers of the two ends of the corresponding main frame, and six hinges are arranged on the connecting frame and the two main frames. The assembly difficulty of a cubesat is lowered, and the integrity of innerlayout is improved. According to the six-unit cubesat main force bearing structure, the main frames are of an integrated structure and connected through the connecting frame making contact with the main frames in a large area so that the parallelism between guiding rails can be ensured, the six-unit cubesat main force bearing structure and a cubesat-rocket separating device are not jammed in launching, and successful launching is ensured.

Description

technical field [0001] The invention belongs to the technical field of cube satellites, in particular to a main load-bearing structure of a six-unit cube satellite. 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] 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 commercialize...

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
