This document discusses vibration in machines and methods to control it. It notes that vibration can cause foundation and machine failure, wear, noise, fatigue failure, and excess stresses. It describes controlling vibration through the use of snubbers in refinery plants, as well as other methods like damped machining tools, balancing rotating mass, vibration isolation, dynamic vibration absorbers, active control, and input shaping. Vibration isolation is defined as the process of isolating an object from vibration sources, and can be done actively using electric power, sensors and actuators.

1. VIBRATION ISOLATION &
CONTROL
-Best way to prevent machine foundation failure!

2. Vibration
 Foundation failure, Machine Failure
 Wearing of the machine
 Undesirable energy waste
 Unwanted noise
 Fatigue Failure occurs
 Reduces the reliability
 Excessive stresses in machine
elements

3. Controlling the
Vibration
Process of reducing the
effect of vibration in
machine component.
Like in refinery plants,
snubbers are often
used for vibration
control.
Snubbers come in two
different variations:
hydraulic snubber and
a mechanical snubber.
Hydraulic Snubber
Mechanical Snubber

4. Methods to control
Vibration
 Damped Machining Tools
 Balancing of Rotating Mass
 Vibration Isolation
 Dynamic vibration absorber
 Active vibration control
 Input Shaping

5. Vibration Isolation
Process of Isolating an object (ground.
machine) from the source of vibrations.
Active Vibration Isolation using Electric
power, Sensors and Actuators
