Large box plate type communication cabin structure

Abstract

A large box plate type communication cabin structure is geometrically divided into partition plates and outer plates from inside to outside, and a cabin space is divided into a lower cabin, a middle cabin and an upper cabin from bottom to top by two layers of horizontal plates. From the assembling relation, the lower cabin partition plate, the middle cabin partition plate, the two layers of horizontal plates and the south and north outer plates are not detachable, and an inner framework with the general assembly modularization manufacturability is formed. The upper cabin partition plate and the opposite floor are non-detachable, so that an antenna cabin structure with local general assembly modularization manufacturability is formed; ten east-west plates, the antenna cabin structure and the inner framework are mutually detachable; in the aspect of a force transmission system, large-mass loads of the communication cabin are mainly distributed on east, west, south, north and earth outerplates, and the large-mass dispersed loads are gradually concentrated from the outer plates and finally gathered to platform cabin connectors of the communication cabin. The communication cabin structure provided by the invention provides a cabin body outer surface load mounting area of up to 40m<2>, and ensures the connection requirements of large-area load, large-path transponders and large-areaload cabin heat dissipation.

Description

technical field [0001] The invention relates to a large-scale box-plate communication cabin structure, which belongs to the technical field of satellite structure design. Background technique [0002] At present, the satellite structure with the largest carrying capacity is the communication satellite. The existing technology adopts the central load-bearing cylinder configuration. The maximum carrying capacity of the traditional communication satellite structure in my country is about 5600kg, with a communication payload of 600kg and a transponder channel of 24. On the other hand, in order to meet the greater load-carrying demand and improve the international competitiveness of my country's commercial satellites, it is urgent to develop a satellite communication cabin structure that can be adapted to increase the maximum load-carrying capacity. [0003] In the existing communication satellites with a weight of about 5600kg, the corresponding structure is the configuration sch...

Problems solved by technology

[0004] The existing pure deck structure satellites basically rely on the force transmission system from the outside to the inside of the bulkhead and the outer plate to the support point of the cabin. Due to the relatively long path of force transmission from the outside to the inside, the structural efficiency is low, and because the pure The load-carrying capacity of the deck-type local joint is small, and this type of structure is more commonly used in the field of small spacecraft of 1500kg or less
