Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] The special metal rubber shock absorber for spacecraft shown in the accompanying drawings includes: a shell 4, a bottom cover 1, a central shaft 2, a shock absorbing element and a bellows protective cover.

[0024] The casing 4, the bottom cover 1, and the central shaft 2 are all made of high-strength aluminum, which reduces the weight of the shock absorber while ensuring the strength of the shock absorber.

[0025] The housing 4 is connected to the bottom cover 1 through threads, and the inner cavity is used to contain and protect the vibration damping element.

[0026] The bottom cover 1 is disc-shaped, and four cylindrical through holes are evenly distributed on the outer surface. When the present invention is applied, the bottom cover 1 is fixed on the substrate by bolts.

[0027] A cylindrical groove is also processed in the center of the top sur...

Abstract

The invention relates to a special metal rubber shock absorber for a spacecraft, and the shock absorber comprises a shell, a bottom cover, a central shaft, two groups of shock absorption elements and a corrugated pipe dust shield. Each group of shock absorption elements is composed of a metal rubber component and a cylindrical compression spring, wherein the cylindrical compression spring sleeves the outer side of the metal rubber component, and the cylindrical compression springs and the metal rubber components form a relationship of parallel connection; the corrugated pipe dust shield is composed of a lower flange, a triangular corrugated pipe and an upper connecting piece which are welded into an integral whole by adopting electron beams. The special metal rubber shock absorber has the characteristics of outstanding shock absorbing effect, small size, light weight, good environment adaptability, stable performance, long service life and the like, and is especially suitable for the shock absorption of precise instruments in the special fields such as aviation and spaceflight.

Description

technical field [0001] The invention belongs to a vibration damping and buffering device, in particular to a special metal rubber damping device used for vibration damping and buffering of instruments and equipment in spacecraft. Background technique [0002] The spacecraft will have adverse vibration effects on various equipment and instruments in the cabin during the launch process and in-orbit flight phase. In order to ensure the performance of the equipment and instruments in the spacecraft and improve the reliability and service life of the equipment and instruments, In order to adapt to the vibration and shock environment of different working conditions of the spacecraft, vibration reduction treatment is required. Early spacecraft shock absorbers generally used rubber shock absorbers, and their elastic damping materials were mainly rubber and its composites. Due to the extremely harsh environment of spacecraft flight, rubber is prone to chemical reactions with ozone a...
