Abstract
The Microgravity Active Vibration Isolation System (MAVIS) onboard the Chinese Space Station's Fluid Physics Research Rack (FPR) isolates the rack from disturbances. In-orbit tests show MAVIS achieves a microgravity level of 1–30 µgo (0.01–125 Hz) and attenuates disturbances above 2 Hz by more than tenfold. Under vibration excitation, it produced a minimum acceleration of 0.4091 µgo (0.00995 Hz) and a maximum of 6253 µgo (9.999 Hz), providing a stable environment for microgravity experiments.
