Regarding vibration absorber, the flex absorber should be fastened to the unit or to a wall at the end pointing away from the vibration source.

• A. True
• B. False
• C. Not applicable
• D. Only to the source

Answer: (A)

Vibration absorbers isolate by placing a flexible link between the vibrating equipment and the structure that could carry the vibration. By fastening the end of the flex absorber that is farthest from the vibration source to the unit or to a wall, you effectively position the compliant element directly in the path of energy transfer. This lets the absorber absorb and dissipate some of the vibration before it can reach the structure, reducing transmitted vibrations and motions.

If you were to attach the end toward the vibration source instead, the path for vibration to reach the support would be less isolated, making the absorber less effective at damping the transmitted energy. That’s why connecting the far end to the unit or wall is the proper setup.
