The attractions of this method include: (1) specimen preparation and experiment procedures are not complicated and (2) the isolation of the micro-vibration is not necessary in the experiment.
The design principles and relevant test results regarding the active suppression of micro-vibrations are presented.
The micro-vibrations generated by equipment onboard spacecraft can significantly affect the performance of sensitive payloads; in particular mid to high frequency band micro-vibrations, are difficult to model and control.
Chen et al. [18, 19] demonstrated that micro-vibration was closely related to air vortices that appeared near the air inlet of the aerostatic bearings and that the strength of these air vortices could be represented by a pressure drop from the edge of the vortex to its center.
Vibration isolation platform is widely used to isolate the micro vibration that is harmful to the sensitive payloads on satellites.
Your vibration is elevating.
An example of air vibration is "f.
Finally, the micro-vibration model is applied to a commercial RWA and the model parameters are extracted from the disturbance test data of the RWA using the parameter estimation process.
Micro-vibration isolation is a hot topic in spacecraft vibration control, and fluid based vibration isolators alternatively provide a good and reliable solution to this challenging issue.
Then, the micro-vibration model is extended to consider an axial disturbance and a measurement offset effect.
The vibration was applied for 6 minutes (Vibration), followed by 2 minutes of post-vibration period (Post-vibration).
