Since ARIS is one player in an integrated ISS vibration isolation strategy. It is critical that we understand its capabilities and limitations on orbit. Experiment to determine functionality of ARIS unit.
Testing is heavily reliant on ground commanding.
The shaker unit provides a precise measurable disturbance in order to simulate possible Space Station disturbance environments. ARIS achieves this disturbance reduction using a combination of sensors and actuators. When sensors detect disturbances from the Space Station, the actuators work to counter the effects of vibrations by delivering a reactive force between the payload rack and the laboratory module. In this way, it performs like a powered shock absorber, acting as buffer between the experiments and any outside disturbances. Much more complex than traditional shock absorbers, ARIS is a finely tuned system with multiple components.
