Description
Technical field
The present invention relates to the technical field for satellite micro-vibration passive damper, be specifically related to a kind of containing stream
The Double-level Reticulated structural vibration reduction device of body damping.
Background technology
Micro-vibration is suppressed, it is first of all clear that the characteristic of vibration source, such as producing cause, the excitation side of vibration source
Formula, vibration source vibration characteristics etc..For the satellite platform of state in-orbit, from the factor causing vibration from the point of view of,
Vibration source on satellite can be divided into external disturbs source and source is disturbed in inherence.
The external source of disturbing specifically includes that the collision of solar radiation optical pressure, particulate, the sun and lunar gravitation, track
Ellipse, compression of the Earth impact, earth gravitational field etc..These are scratched, and the vibration frequency in source is extremely low (typically to exist
Below 0.01Hz), vibration amplitude little (being usually no more than 10-6g), long action time (is equal to spacecraft exist
The rail flight time).This kind of vibration is considered as the most often the ambient interferences of the quasi-steady state acceleration being difficult to elimination,
Mainly affected by the Track desigh of satellite.Owing to load is insensitive to this kind of vibration, its impact is the least,
Micro-vibration control is not typically considered.
Inherence disturb source mainly due to the heat control system of satellite, attitude control system, air-conditioning system, power-supply system,
The motions of the parts such as solar wing etc. are caused.This kind of the vibration source mainly (> 0.001Hz based on medium-high frequency), magnitude
Can reach 10-2g.Wherein, intermediate frequency (0.001Hz～1Hz) scratches source typically by load or the instantaneous row of astronaut
By being produced；High frequency (> 1Hz) scratch source typically by reaction wheel, momenttum wheel, compressor, water pump, propelling
Device igniting etc. causes.This source of scratching this kind of has frequency range width, presents the characteristic of low-frequency high-amplitude, frequency low-amplitude simultaneously,
It it is the main vibration source that load performance on spacecraft is produced interference.
The reciprocating motion when purpose of micro-vibration control is that satellite operation on orbit is reduced or eliminated is to payload
Can adverse effect, as the control of its controlling soil moist and conventional vibration, also from vibration source, pipeline and controlled
Object is started with.Conventional vibration isolation measure has: vibration source is taked vibration isolation measure weaken the impact of vibration source；To transmission
Path (structure) is optimized, and reduces bang path response under load effect；Use load isolation skill
Art, i.e. adds isolation mounting between load and mounting structure, reduces the structural vibration impact on load.
But existing isolation mounting structure is complicated, rigidity is big, and shock-absorbing capacity is poor.
