A gas cylinder bracket for spacecraft

Abstract

The invention provides a gas cylinder support for a spacecraft. According to the gas cylinder support, gas cylinders can be arranged in a concentrated mode, the layout space is saved, the space utilization rate is improved, the force transferring route is direct, environment conditions are excellent, the bearing ratio is high, and the dynamic characteristic is good. The gas cylinder support comprises a gas cylinder installation plate and supporting plates, the gas cylinder installation plate and the supporting plates are carbon fiber skin aluminum honeycomb sandwich plates, the gas cylinder installation plate is installed on a center force bearing barrel, gas cylinder installation connectors with the same number as gas cylinders are evenly distributed on the upper surface of the gas cylinder installation plate in the circumferential direction, and each gas cylinder installation position on the lower surface of the gas cylinder installation plate is provided with one supporting plate. Each supporting plate is connected with the gas cylinder installation plate through a lateral embedded part; meanwhile, the supporting plates are connected with the center force bearing barrel through connection corner strips, and at least one supporting plate is connected with a middle plate through a connection corner strip.

Description

technical field [0001] The invention relates to a gas cylinder bracket, in particular to a gas cylinder bracket that can be used for a center-bearing cylindrical satellite, and belongs to the field of spacecraft and structural design. Background technique [0002] At present, in the center bearing tube satellites with successful flight experience in China, the gas cylinders are connected in such a way that the lower end is directly connected to the middle plate through the flange, and the upper end is connected to the central bearing tube through the gas cylinder tie rod. And the three gas cylinders are distributed in the three quadrants of ±X of the middle plate respectively. This type of connection is simple and does not require other auxiliary support facilities. However, due to the direct effect on the mid-plate, the response of the gas cylinder is greatly affected by the mid-plate, and the local frequency is low, and the response of the gas cylinder at the longitudinal...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that the current gas cylinder support structure used for the center-bearing cylindrical satellite cannot meet the requirements of centralized arrangement of gas cylinders, overall disassembly and assembly, improvement of space utilization, and reduction of layout area.
