A main structure of plate and pole satellite

Abstract

The invention discloses a plate-and-rod satellite main structure, comprising: a docking ring, a main load-bearing partition, a first rod system, a second rod system and a rectangular box; the upper end surface of the docking ring is provided with a main load-bearing connection method Lan; the back floor of the rectangular box is fixed on the docking ring; the main load-bearing partition is installed in the rectangular box, and the inner cavity of the rectangular box is divided into two identical cavities, and the main load-bearing partition There are two V-shaped load-bearing beams embedded in the panel; after the two ends of the V-shaped structure pass through the back floor respectively, they are connected with the main load-bearing connecting flange on the docking ring; the same first bar system and the second rod system are respectively installed in two identical cavities, and after passing through the back floor respectively, they are connected with the main load-bearing connecting flange on the docking ring in one-to-one correspondence; the load-bearing capacity of this structure can reach a medium-sized satellite Requirements, the structure has good openness, which is beneficial to the assembly operation, the equipment is easy to layout, the cabin has a large capacity, and the structure has a small dry weight, so as to realize the efficient load bearing of the structure.

Description

technical field [0001] The invention belongs to the technical field of spacecraft structures, and in particular relates to a plate-and-rod type satellite main structure. Background technique [0002] The main functions of the main load-bearing structure of the satellite are: to bear the dynamic load and static load of the satellite launch section, to ensure that the structure is not damaged or deformed; to provide installation interfaces for on-board equipment and maintain stable accuracy. [0003] There are three commonly used structural forms for the main satellite structure, namely, the load-bearing cylinder type, the box-plate type and the truss type. The satellites of the three structural forms have their own characteristics. [0004] Bearing-tube satellites are mostly used for medium-sized and large-scale satellites, with relatively strong carrying capacity. The storage tanks are usually installed in series up and down, with a high center of mass and poor structural o...

Problems solved by technology

[0004] Bearing tube satellites are mostly used for medium-sized and large satellites, with relatively strong carrying capacity. The storage tanks are usually installed in series up and down, with a high center of mass and poor structural openness, which is unfavorable for equipment layout. inconvenient

The box-plate satellite has a flat equipment installation surface, large cabin capacity and is conducive to equipment layout, but the local strength of the box-plate satellite's main load-bearing structure is low, and the local load capacity of the connection between the plate and the docking ring is small, which is only suitable for small satellites

The truss-type satellite has a strong carrying capacity and is suitable for large and super-large-scale satellites. The truss-type satellite is mostly suitable for large-scale concentrated load transfer, and the concentrated load is transferred through the truss connection point. It is not suitable for decentralized load and highly integrated small and medium-sized satellites.
