Open type assembling module platform cabin structure

Abstract

The invention provides an open type assembling module platform cabin structure, which belongs to the technical field of spacecraft structures and comprises a plate type cabin body, a standard replaceable module and a standard butt joint interface, wherein the standard replaceable module is mounted on the plate type cabin body through the standard butt joint interface; the plate type cabin body isof a grid-type frame structure and is of a front-and-back open type and symmetrical type; the standard replaceable module and the plate type cabin body are combined to form a drawer-type structure, and the standard replaceable module can be captured, pulled out and pulled out of the platform cabin for on-track maintenance by means of a robot. The structure is suitable for the high-orbit ultra-large assembling maintainable satellite platform, can be used as a component of the ultra-large satellite platform, and can also be used as a transportation tool for carrying out modular single-machine on-orbit maintenance on the ultra-large satellite platform; the module platform cabin is extensible in structure, the number and the size of standard modules can be designed, the overall structure is high in universality, the structure is simple, batch production is easy, and the development cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of spacecraft configuration, in particular to an open modular platform cabin configuration that can be assembled. Background technique [0002] In recent years, in order to make full use of valuable geostationary orbit resources, ease the fierce competition for orbital positions, and break through the constraints of the carrying capacity on the size of satellites, ultra-large on-orbit assembleable satellite platforms have become the development trend of high-orbit satellites. In order to alleviate the problems of large-scale satellite platform development and high launch costs, and to meet the long-life requirements of very large satellites, on-orbit maintainability based on modular design has become a basic requirement for very large satellite platforms. The modular design is conducive to the timely replacement of the faulty single unit by the satellite platform, which is convenient for the replacement of a...

Problems solved by technology

In recent years, research on the modular design of satellite platforms has aroused widespread interest among domestic spacecraft designers. Patent document CN107697317A discloses a modular micro-nano satellite platform, in which a group of stacked frames are connected in series by four screws into An integrated satellite platform, the satellite platform subsystem is installed inside the laminated frame; the patent document CN103482082A discloses a modular micro-satellite platform configuration, which is a box-type hexahedron body configuration composed of a bottom plate, a top plate and a side plate. The sub-system modules are installed on the inner side of the side plate; the patent document CN104290920A discloses a modular reconfigurable micro-nano satellite structure. Stand-alone standard interface, the combination of different stand-alone loads can be realized through the assembly of different side plates, so as to achieve the reconstruction of the satellite platform; but the modular design in the above three documents is mainly for an independent single micro-satellite, and the satellite platform does not have Assembly capability, and the satellite body is a closed configuration, which is not convenient for on-orbit maintenance

[0004] In addition, the patent document CN106628253A discloses a vertebral-column modular satellite platform architecture, which adopts a vertebral-coaxial configuration. The stand-alone module is arranged on the star table through a standard interface, and has a plug-and-play function. However, this satellite platform The body is in an irregular configuration, the space utilization rate is low, and it does not have the ability to assemble
