Vibration analysis is becoming more and more well-known as a prognostic maintenance procedure as well as a support for machinery maintenance judgment and decisions. Generally, machines don’t fail, malfunction, or break down without showing some symptoms or warning, which is often shown by an amplified level of vibration. To find out the nature and harshness of the machine flaw, and to therefore predict the failure of the machine or equipment, vibration measurement and analysis should be conducted.

A machine has an overall vibration signal that comes from the several components and structures infused into it. Mechanical problems, however, create distinctive vibrations at varying frequencies. And these defects as well as the natural frequencies of different structural elements can be diagnosed by analyzing the frequency and time range and employing signal processing skills.
