Abstract

The invention provides an antenna support and a spacecraft. The antenna support comprises a support body and at least one sealed compartment, the support body at least partially penetrates through each compartment, and viscous fluid is poured into the compartments. According to the invention, based on the principle of tuning liquid damping, the support body, the compartments and the viscous fluidform a damping and buffering device. In the launching stage of the spacecraft, vibration and impact of the spacecraft are transmitted to the bottom end of the support body, so that the viscous fluid in the compartments shakes, dynamic side pressure is generated on the support body, and the acceleration response of the top end of the support body is reduced; meanwhile, the oscillation of the viscous fluid can effectively absorb and consume the vibration energy of the support, so as to achieve the effects of damping and buffering, reduce the acceleration response of the antenna load at the launching section of the spacecraft, and improve the adaptability and reliability of the antenna load and the support body.

Description

technical field [0001] The invention relates to the technical field of aerospace equipment, in particular to an antenna bracket and a spacecraft. Background technique [0002] The low-orbit broadband communication satellite communication load usually has a reflector antenna load of the mechanical scanning working system. In order to avoid rotation interference, antenna loads such as antenna loads and servo shafts need to be fixedly connected to the star through mounting brackets, and the shaft is supported to a certain height from the star. The mounting bracket plays the role of bearing mechanical loads such as vibration and impact of the antenna load in the transmitting section. [0003] The mounting bracket is generally formed by precision machining through an aluminum alloy thick plate. The bottom is the mounting interface with the star, and the upper part is the mounting interface with the antenna load. [0004] In the prior art, the antenna load mounting bracket has a...
