Abstract

The invention discloses a small satellite polygonal force bearing barrel which comprises a barrel body. An upper end frame is glued at the top of the upper end of the barrel body in an embedded mode, a lower end frame is glued at the bottom of the lower end of the barrel body in an embedded mode, purlin strips are arranged at corners of the barrel body, a trepanning reinforcement frame is connected to the trepanning position of the barrel body in a glued mode, and a reinforcement corner box is arranged at the upper end of the lower end frame. The small satellite polygonal force bearing barrel solves the problems that the mass of the force bearing barrel is large, inconvenience is brought to installation on the surface of the barrel body, and the structural mode is complex, and has the advantages of being simple in structure, light in weight, multiple in installation face and the like.

Description

technical field [0001] The invention relates to a load-bearing structure for the main load of a satellite, in particular to a polygonal load-bearing cylinder applied to a small satellite. Background technique [0002] The load-bearing tube is the load-bearing structure that carries the main load of the satellite. It is the core of the satellite structure assembly. It can not only directly provide the installation surface of the propulsion system, the interface for the connection and separation of the satellite and the launch vehicle, but also provide design, manufacture, and assembly for the satellite structure. , benchmarks and tests for precision measurements, supports for transport, and interfaces for ground support equipment. Therefore, the load-bearing tube is the key main load-bearing structure that affects the performance of the satellite platform's structural strength, stiffness, and dynamic response characteristics of the entire satellite. Contents of the inventio...
