A kind of liquid damping vibration isolator for satellite

Abstract

The invention discloses a liquid damping vibration isolator for a satellite. The liquid damping vibration isolator comprises a rigidity providing device, a damping providing device and a connecting and fixing device. The rigidity providing device is mainly composed of a left main corrugated pipe, a right main corrugated pipe, a left auxiliary corrugated pipe, a right auxiliary corrugated pipe and a compressing spring. The damping providing device is mainly composed of liquid in a damping disc and the corrugated pipes; the connecting and fixing device is composed of a left connecting cover plate, a right connecting cover plate, a left connecting disc, a right connecting disc, a left cover plate and a right cover plate. The left main corrugated pipe and the left auxiliary corrugated pipe are connected together in a sealing manner through the left connecting disc; the right main corrugated pipe and the right auxiliary corrugated pipe are connected together in a sealing manner through the right connecting disc; the left connecting disc and the right connecting disc are fixed to the left connecting cover plate; the two ends of the left auxiliary corrugated pipe and the two ends of the right auxiliary corrugated pipe are sealed through a left end cover and a right end cover; the damping disc is fixed to the right connecting cover plate; the end of the left connecting cover plate and the end of the right connecting cover plate are provided with threads connected with an external structure; and the compressing spring is arranged on the left auxiliary corrugated pipe. The liquid damping vibration isolator is used for micro vibration isolation between a sensitive load component on the satellite and the satellite and also used for isolation of a vibration component on the satellite.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a liquid damping vibration isolator for satellites. Background technique [0002] With the development of high-resolution satellites, the vibration requirements on stars are becoming more and more stringent. In order to further improve the performance of satellites for earth observation and improve the micro-vibration environment of satellites, the application of vibration isolation technology has become urgent. However, traditional vibration isolators will inevitably encounter the effects of temperature, volume, weight, and radiation when used on stars. In order to adapt to the small design space, low weight and mature materials of the satellite, the effective realization of the micro-vibration isolation function on the satellite has great application value and development prospects for the improvement of the vibration environment that affects the performance of the satellite...
