introduction Vibration Control
There are numerous Sources of Vibration in an Industrial Environment
•
Presence of Vibration leads to
•
Excessive wear of bearings,
•
Formation of cracks,
•
Loosening of fasteners,
•
Structural and mechanical failures,
•
Frequent and costly maintenance of machines,
•
Electronic malfunctions
•Exposure of Humans leads to Pain, Discomfort and Reduced efficiency.
Hence it is necessary to eliminate or reduce vibration
Vibration Isolation
Isolating the structures from vibration is very important
Accuracy of the machines
Comfort levels of the passengers
Transmission of vibrations to other nearby equipment
Sound Generated due to the vibration is to be in limits
Vibration of the buildings due to the equipment present in them
Forced Damped Vibration Absorber
Solving the above equation , we get
All Curves with different Damping pass through points P and Q
Hence it is possible to find the optimum Damping value
