Abstract

The invention discloses a 2U cubesat structure which comprises side face frames, crossbeams and connecting screws. Each side face frame is composed of a rectangular truss and a reinforcing rib plate,and the crossbeams and the connecting screws are connected. The 2U cubesat structure is composed of two 1U structures, different layers are distributed in each 1U structure, and different function units can be installed on the different layers. The 2U cubesat structure is a standardized design structure, the function units can be installed in the standardized structure, through the modularized design structure, the structure is simple and easy to install, under the condition that the structural strength meets the requirement, a new material is adopted, mass is small, and cost is low.

Description

technical field [0001] The invention relates to the field of cube star equipment, in particular to a 2U cube star structure. Background technique: [0002] With the development of microelectronics technology, new materials, new energy and other technologies, the application of microsatellites has developed rapidly. At present, they are mainly used for communication, remote sensing of the earth, interplanetary exploration, scientific research and technical experiments, etc., and also have military applications.
