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. Unfortunately (but
Vibration isolation is defined as the process to isolate an object from sources of vibration. The theory of vibration isolation is to make the natural frequency of the system lower than the forced frequency and to suppress the resonance at the natural frequency of the system. As technology advances. a vibration isolation technique is ...
Vibration Isolation. In a passive isolation system, two factors affecting isolation efficiency are the natural frequency and damping of the isolator. – The natural frequency is the rate of free oscillation per unit time and damping is the characteristic which dissipates energy in a dynamic system.

Vibration Isolation of Machines / Equipment The Single-Degree-of-Freedom System. The simplest way to describe a vibrating system is a single degree-of-freedom system (SDOF system). An inert mass sits on a rigid base, separated by an elastic element. The machine (mass) is separated from its environment by a spring and a damper.
