Abstract

The invention discloses a new truss-type satellite main structure public platform, which consists of a star-shaped central load-bearing frame (1), a bottom plate (2), a pair of ±Y-directed side plates (3) parallel to each other, and a pair of ±X-directed The side plate (4) is composed of; the star-shaped central bearing frame (1) includes the star-arrow docking ring (11), one X-direction W-shaped plane truss (12) and two symmetrically distributed Y-direction W-shaped plane trusses (13 ); 3 W-shaped plane trusses are star-shaped, i.e. distributed in a * shape, connected as a whole and connected to the side plates respectively; 3 W-shaped plane trusses are connected to the star arrow docking ring (11) through the bottom outer joint (129); The bottom plate (2) is connected with the star arrow docking ring (11) at the position of the opening in the middle. The platform of the present invention meets the satellite layout requirements while ensuring a reasonable force transmission path, can carry various types of payload compartments (or modules), and is suitable for use when the weight of the entire satellite exceeds 6 tons and the diameter of the storage tank is greater than 1 meter.

Description

technical field [0001] The invention relates to satellite main structure configuration technology, in particular to a truss-type satellite main structure common platform. Background technique [0002] The main structure of the satellite is docked with the launch vehicle, and the load is transferred from the launch vehicle to the satellite, forming the main force transmission path. The main structure of the satellite is classified according to the form of the structural components, which can generally be divided into three types: the load-bearing cylinder type, the box-plate type and the truss type. The three structural forms have their own characteristics. [0003] In a satellite with a load-bearing cylindrical structure, the storage tanks are usually installed in series up and down. For payloads with heavy weight and high center of mass, it is not convenient to install on this type of satellite platform. The local strength of the box-plate main load-bearing structure is lo...
