Two areas have been highlighted on THE GRAPH:
1. Area of resonance:
A device is in this area if the ratio fwym/fwib is close to unity. The amplitude of deterministic vibration increases repeatedly which can cause a device’s irreversible damage.
2. Area of effective dampening:
for a device to remain in this area, a vibration isolator has to be selected, so that the fwym/fwibratio is higher than 1,42. The highest effectiveness of vibration isolation (over 90%) is achieved if the ratio is higher than 3,5.
The green curve presents the dependency between the percentile effectiveness of vibration isolation and the fwym/fwib ratio.
