Abstract

The invention provides a lower frame structure suitable for a satellite load-bearing cylinder, which relates to the technical field of spacecraft structures, including the connection section between the lower end frame and the load-bearing cylinder body, the connection section between the lower end frame and the carrying and the connecting piece, and the carrying of the lower end frame. The connecting section and the connecting section of the load-bearing cylinder of the lower end frame are connected by a connecting piece, wherein the lower end frame and the carrying connecting section are made of aluminum alloy material, and the connecting section of the lower end frame and the bearing cylinder is made of carbon fiber material. The lower end frame of the load-bearing tube of the arrow interface, a split structure of the lower end frame of the satellite load-bearing tube is designed, which improves the problem of the heavy weight of the lower end frame of the original satellite load-bearing tube, and ensures that the lower end frame can withstand a large concentration. Under the premise of load, the structure weight can be reduced to the greatest extent, which meets the requirements of lightweight satellite structure. The processing and molding technology is mature, the installation is convenient, and the structure is simple.

Description

Technical field [0001] The present invention relates to the field of spacecraft structures, and in particular, to a lower end frame structure suitable for satellite support. Background technique [0002] The lower end frame of the satellite stripping cartridge is a structural member necessary for a stable shape that has a stable shape, a completely independent housing structure, is a structural member that is subjected to load in the entire carrier. [0003] At present, there are two basic structures of the lower end frame below the lower end frame: the lower end box does not include the star arrow interface, the lower end box contains an arrow interface. Patent Document CN103448919A discloses a carbon fiber sheet reinforcing strip of the satellite structure, including a connected cone section and a column segment, a cone section and a column section, and a cone section is laid on the column section. The upper end of the skin, the upper end of the column extends the upper frame, ...
