Abstract

The invention relates to a vibration absorption device suitable for a satellite platform and a using method, and the vibration absorption device suitable for the satellite platform comprises a base which is connected to the satellite platform, and the satellite platform is provided with vibration equipment and a sensitive load. A plurality of groups of vibration absorption assemblies are arranged on the base, each group of vibration absorption assembly comprises a mounting rod connected to the base and a mass block assembled on the mounting rod in an exchangeable manner, and the mounting position of the mass block on the mounting rod is adjustable. A mass spring damping system can be formed through the mounting rod and the mass block assembled on the mounting rod, the inherent frequency of the vibration absorption assemblies can be adjusted through the replaceable mass block and the adjustable position of the replaceable mass block on the mounting rod, and resonance of vibrations caused by the vibration absorption assemblies and vibration equipment is facilitated. Therefore, vibration energy generated by the vibration equipment is transferred to the vibration absorption assemblies in a mode that the base is connected with the satellite platform, so that the micro-vibration effect of the system is reduced.

Description

technical field [0001] The present application relates to the technical field of satellite vibration reduction, in particular, to a vibration-absorbing device suitable for a satellite platform and a method of use. Background technique [0002] With the rapid development of the aerospace industry, high-precision sensitive loads have higher and higher requirements on the micro-vibration environment of satellite platforms. Especially for some high-resolution optical payloads, the micro-vibration environment has gradually become one of the key factors affecting the performance of the entire system when the satellite is in orbit. [0003] Satellite platform microvibration refers to a vibration response with small amplitude and relatively high frequency generated by some rotating parts in the satellite platform during the on-orbit operation phase; it usually includes propulsion ignition, load azimuth and Mechanism movements such as pitching and rotation of other high-speed rotati...
