Abstract

The invention discloses a CubeSat framework based on 3D printing, which comprises a side frame and a connecting screw rod, and further comprises fixing tables and a solar cell panel, four fixing tables are connected in the side frame, the surfaces of the fixing tables are connected with the connecting screw rod, the outer surface of the connecting screw rod is sleeved with a circuit board. A large circular hole and a small circular hole are formed in the outer surface of the side frame, and a power switch is arranged on the inner side wall of the side frame. According to the CubeSat framework based on 3D printing, the selective laser melting metal 3D printing technology is adopted, the structural strength of the CubeSat framework reaches up to 500 MPa, the weight of the CubeSat framework is half of that of a traditional method, the design and manufacturing period is shortened, and on the basis that an original CubeSat framework loads different functional loads, the strict requirement of a spacecraft for the load quality can be better met.

Description

technical field [0001] The invention relates to the technical field of cube stars, in particular to a cube star frame based on 3D printing. Background technique [0002] With the rapid development of microelectronics and micromechanical technology, microsatellites have developed rapidly, among which the development of cube satellites is particularly eye-catching. At present, they are widely used in remote sensing of the earth, communication applications and even deep space exploration. Especially as the functional density of CubeSat continues to increase and its low cost, more and more satellite projects are completed in the form of CubeSat. [0003] CubeSat is a kind of small satellite widely used in universities to carry out space science research and education in the world. It has the characteristics of low cost, high functional density, short development cycle, and fast entry into orbit. Through networking to form a constellation, it can realize the ocean, Monitoring of...
