Vibration isolation and piston type buffering system for satellite flywheel vibration isolation support

Abstract

The invention discloses a vibration isolation and piston type buffering system for a satellite flywheel vibration isolation support. The vibration isolation and piston type buffering system comprises a vibration isolator, movable pieces, damping pieces, fixed pieces and a piston type buffering device, wherein the movable pieces, the damping pieces and the fixed pieces are arranged on the outer side of the vibration isolator; the piston type buffering device comprise a movable rod, a bush, a fixed rod, a piston rod, a first buffering piece, an inner sleeve and a second buffering piece; the two sides of the fixed rod and the two sides of the movable rod are connected with the lower end and the upper end of the vibration isolator correspondingly; the middle of the fixed rod is connected with the end face of the bush; the first buffering piece and the second buffering piece are arranged on the inner side of the bush and the inner side of the inner sleeve; a buffering space is formed between the first buffering piece and the second buffering piece; one end of the piston rod is connected with the movable rod; the other end of the piston rod sequentially penetrates through a through hole of the bush and a through hole of the first buffering piece and extends into the buffering space; and the movable rod drives the piston rod to move in the buffering space between the first buffering piece and the second buffering piece. The vibration isolation and piston type buffering system has the advantages of being light in mass, small in size, simple in structure, convenient to assemble, low in manufacturing cost, high in adaptability, high in university and the like.

Description

technical field [0001] The invention relates to a system, in particular to a vibration isolation and piston type buffer system for a satellite flywheel vibration isolation bracket. Background technique [0002] The performance of optical satellites is developing in the direction of high precision and high stability, so it is very important to reduce the vibration interference caused by the flywheel. At present, this purpose can be achieved by installing a passive vibration isolation bracket between the flywheel and the star, but the vibration isolation bracket has low stiffness and cannot safely pass through the active launch section. Adding an unlocking device to the vibration isolation bracket will increase the system quality, resource requirements, layout difficulty, and reduce system reliability. Therefore, it is necessary to design a system that allows the vibration isolation bracket to pass through the active section so that the vibration isolation bracket does not dam...
