While the shaker operates, the armature and table are lifted by compressed air through four cushions at the bottom of the shaker table. This provides excellent stability. A set of amplifiers, monitors, sensors and controllers is used to ensure the shaker operates correctly. The drive signals are defined according to the specifications of the control system.
The shaker table has been used for a variety of cases in both commercial and academic research including testing computer systems, electronic boxes, oil pumps, and spacecraft mechanisms and structures etc.
