12. VIBRATION ISOLATION
12.1 Introduction. High vibration levels can cause machinery failure, as well as objectionable noise levels. A common source of objectionable noise in buildings is the vibration of machines that are mounted on floors or walls. Obviously, the best place to mount a vibrating machine is on the ground floor.

Vibration Isolation
Vibrations originating from machines or other sources are transmitted to a support structure such as a facility floor, causing a detrimental environment and unwanted levels of vibration. If the equipment requiring isolation is the source of unwanted vibration, the purpose of isolation is to reduce the vibration transmitted from the source to the
Vibration Isolation Basics
Isolation is the prevention of vibrations from entering Damping is the absorption of the vibration energy that is entering system and dissipating it by changing the kinetic energy of into a different form of energy. The two forms of vibration ment are different from each other, but often are used in conjunction to achieve the desired performance.

What is Vibration Isolation? | Isolation Dynamics Corp
Isolation is the reduction in vibration transmitted to an object. Vibration isolators suppress unwanted vibrations by reducing the system's natural frequency below its excitation frequency. A damper reduces unwanted vibrations by absorbing vibrational energy. Most isolators work through the combination of an elastic element, such as a spring, with a …
Vibration-Isolating Mounts
Vibration-isolating mounts have solid rubber bodies with threaded studs or tapped holes on one end for mounting. Also called bumpers, they absorb impact energy, dampen shock, sound, and rebound, and serve as end-stop bumpers or set-up elements for conveyors, machines, and assembly systems. Tapped Bullet-Nose Vibration-Isolating Mounts.

Vibration Isolation Theory
Vibration is an oscillatory motion. Any body with mass and elasticity can vibrate. The simplest type of vibrating system is called a single-degree-of-freedom spring-mass system. The spring is characterized by its spring rate, K, and a mass, M. This system is called a single-degree-of-freedom system because motion can occur in only one direction.
