Abstract

The invention relates to the technical field of momentum wheel micro-vibration isolation, and provides a remote sensing satellite momentum wheel vibration isolation bracket and a manufacturing methodthereof. The vibration isolation bracket is provided with a momentum wheel connecting piece corresponding to a momentum wheel mounting hole in the momentum wheel bracket, a first limiting groove is formed in the inner side wall of the momentum wheel mounting hole, a second limiting groove is correspondingly formed in the outer side wall of the momentum wheel connecting piece, the first limiting groove is connected with the corresponding second limiting groove through a vibration isolation pad, due to the fact that the vibration isolation pad has good stiffness and damping characteristics, during the satellite launch phase, vibration transferred from a satellite capsule plate to the momentum wheel bracket is transferred to the momentum wheel after attenuation of the vibration isolation pad,the mechanical environment of a momentum wheel can be improved, and it is ensured that the momentum wheel is not damaged by overload; and micro-vibration generated by the momentum wheel is finally transferred to the remote sensing load after vibration attenuation of the vibration isolation pad during in-orbit imaging of a satellite, the influence of disturbing force of micro-vibration on the camera visual axis can be controlled within the technical requirements of a camera, and the imaging quality of the remote sensing camera is ensured.

Description

technical field [0001] The invention relates to the technical field of momentum wheel micro-vibration isolation, and more specifically, to a remote sensing satellite momentum wheel vibration isolation bracket and a manufacturing method thereof. Background technique [0002] When a spacecraft is in orbit, in order to complete its mission, it must have a certain attitude. The camera or other remote sensors of the earth observation remote sensing satellite must be aimed at the ground, and the attitude control of the spacecraft is mainly realized through the momentum wheel, and the momentum wheel will generate micro-vibrations during the working process, which are transmitted to the remote sensing load through the satellite structure deck. Due to the strong directivity of the installation of the momentum wheel, it is necessary to provide a special installation and support special-shaped device for the momentum wheel, that is, the momentum wheel assembly. [0003] The momentum w...
