Abstract

The invention discloses a high-damping vibration isolator used for a satellite sensitive load. The high-damping vibration isolator used for the satellite sensitive load comprises an upper installation unit, a lower installation unit, a main vibration isolation unit and a high-damping unit, wherein the upper installation unit is connected with the satellite sensitive load; the lower installation unit is connected with a satellite body; the upper installation unit, the lower installation unit and the main vibration isolation unit integrally form a unified main vibration isolation structure; the main vibration isolation structure and the high-damping unit are connected in parallel. The high-damping vibration isolator used for the satellite sensitive load disclosed by the invention has the following technical characteristics: I, the installation of satellite sensitive load equipment is ensured; II, vibration transferred to the sensitive load by a satellite platform is isolated to ensure the normal operation and the working quality of the sensitive load; III, the vibration disturbance of the sensitive load is restrained; IV, an impact response brought by deblocking of a satellite initiating explosive device is rapidly damped. While the sensitive load is supported, the goal that the sensitive load can normally work in orbit reliably, safely and effectively is achieved.

Description

technical field [0001] The invention relates to a vibration isolator in the technical field of satellite sensitive loads, in particular to a large damping vibration isolator for satellite sensitive loads, which can effectively isolate and suppress the vibration interference of the satellite platform and the sensitive load itself, Effectively attenuates the explosion unlocking impact of explosive bolts to ensure the normal operation of sensitive loads. Background technique [0002] With the development of satellite technology, the accuracy of satellite sensitive loads is getting higher and higher. At the same time, strict requirements are put forward for the micro-vibration environment of the installation part. In order to meet the needs of satellite attitude adjustment and orbital maneuvering, satellites are equipped with rotating parts such as flywheels or moment gyroscopes, which will inevitably introduce vibration interference sources. According to research, it is found t...
