If the body of a vibrator is mounted on air bags or other types of isolation mounts to reduce vibration into the floor, vibrator
body motion will occur.
As the load mass is increased, the effective relative displacement of the armature to ground is decreased as some of the rated travel is used up in body motion.
This program will determine the maximum displacement available for a given test load.
The calculation for vibrators having an "isolation system" is not applicable if the isolators are at resonance!
