Combined Support Structure for Large Antennas of Deep Space Probes

Abstract

The invention relates to a combined support structure for a large-size antenna of a deep-air detector in the technical field of satellite engineering. The combined support structure comprises a bottomplate support seat, a bearing cylinder support seat and a top plate support truss, wherein the bottom plate support seat employs a U-shaped structure to connect an edge of a bottom plate, the bearingcylinder support seat is connected with a bearing cylinder by a screw, the top plate support truss is in screwed with a top plate, and the connection strength and the connection rigidity are ensuredby a plurality of carbon fiber support rods. The combined support structure can be used for installing the large-size antenna and has the characteristic of large installation space; with a combined design of the bottom plate support seat, the bearing cylinder support seat and the top plate support truss, the combined support structure has the characteristics of direct force transfer path and highbearing capability; the truss support structure employs a carbon fiber composite material, the support seat is of an aluminum alloy thin wall structure and has the characteristics of light weight andsmall response; and the combined support structure can be promoted in an antenna support structure design of other satellite structure platforms and has the characteristic of wide applicability.

Description

technical field [0001] The invention relates to a supporting structure of an antenna, in particular to a combined supporting structure for a large antenna of a deep space probe. Background technique [0002] Large antennas are essential equipment for implementing organ-ground communications for deep-space probes flying over extremely long distances. In order to transmit a large amount of detection data and images to the ground, the problem of extremely long-distance transmission with low data rate must be solved. Deep space probes need to fly an extremely long distance. During the long flight, a large amount of detection data and images must be transmitted to the ground, and at the same time receive relevant information on the ground. Therefore, deep space probes have extremely high requirements for the performance of the antenna. In addition to using technologies such as data compression, anti-jamming and coherent reception on the detector, it is also necessary to increase...
