Abstract

The invention discloses a scrap-leakage-proof metal-rubber damper suitable for in-orbit application of a spacecraft. The metal-rubber damper comprises a metal-rubber pressure plate, a shell, a mandrel, a corrugated tube, a corrugated tube flange, a screw and metal-rubber elements. Vibration energy input by a structure is dissipated through friction among metal wires which are engaged and hooked inside a metal-rubber material, so that the aims of damping and reducing vibration are fulfilled. According to the damper, the metal-rubber pressure plate is in threaded connection with the shell, and preloads are applied to the metal-rubber elements on the upper side and the lower side of the horizontal mandrel to keep the metal-rubber elements in compressed states, so that the stability of the damping performance is ensured. The damper has the advantages of simple structure, convenience in installation, suitability for spatial extreme environmental conditions, and the like.

Description

technical field [0001] The invention relates to a metal-rubber damper, in particular to a debris-leakage-proof metal-rubber damper suitable for spacecraft on-orbit applications. Background technique [0002] With the continuous improvement of the accuracy of the payload of the spacecraft, it is more and more sensitive to the mechanical environment of the spacecraft in orbit. In order to meet the on-orbit working environment requirements of the payload, it is necessary to adopt corresponding vibration suppression measures, such as using a damper to absorb or dissipate the vibration energy transmitted from the vibration source to the payload through the spacecraft structure. Metal rubber dampers have stiffness nonlinearity; good damping and vibration reduction performance; small mass, non-volatile, radiation resistance, resistance to alternating cold and heat, fatigue resistance, long life and high reliability, etc., are very suitable for space environments spacecraft vibrati...
