A multi-functional load-bearing structure for micro-satellites

Abstract

The invention discloses a multifunctional load-bearing structure for miniature satellites. A stand-alone shielding casing, a satellite load-bearing plate and a GNC (guidance, navigation and control) stand-alone are integrated into a square box structure. The square box structure can serve as a stand-alone for installation and degugging or a main satellite load-bearing structure for transmitting external load and has certain expansibility, and other stand-alone can be installed on the square box structure. The multifunctional load-bearing structure is applicable to the miniature satellites with high requirements on integration level; the structure and functional stand-alone are designed integrally, stand-alone structure and satellite structure are combined, and integral assembly is realized; the stand-alone and the structure can be expanded, and multipurpose functions of the structure are realized; multiple functions of the structure do not affect one another, and the structure is high in function density, light in weight, small in size and high in bearing capacity. The multifunctional load-bearing structure can be applied to main load-bearing structures of the miniature satellites and auxiliary load-bearing structures of main load-bearing structures of large satellites.

Description

technical field [0001] The invention belongs to the field of spacecraft structure design, and in particular relates to a multifunctional load-bearing structure for a miniature satellite. Background technique [0002] In the process of aerospace technology development, spacecraft carry a large number of stand-alone equipment and have high-performance structures that carry stand-alone equipment; at present, most stand-alone equipment is still installed in the main structure of the spacecraft, and the structure only has the function of carrying and transmitting loads. Multifunctional structure refers to the use of the same structure to achieve different functions, such as integrating the control circuit, thermal management device, main load-bearing structure and stand-alone interface into a structural product, so that it has the functions of circuit, structure and stand-alone equipment at the same time. An important way to achieve performance improvement and functional integrat...
