Vibration analysis is becoming increasingly well known as a prognostic maintenance procedure as well as a support for machinery maintenance judgment and decisions. Machines do not generally fail, malfunction or break down without displaying some symptoms or warnings, often displayed by an amplified level of vibration. In order to find out the nature and severity of machine failure, and thus predict machine or equipment failure, vibration measurements and analysis must be performed.

A machine has an overall vibration signal that comes from the various components and structures infused into it. Mechanical problems, however, create distinctive vibrations at different 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.

Since vibration analysis deals with all moving components of any type of rotating device, it can pinpoint not only particular machine problems, but can also simplify repairs by pinpointing the source or root cause of the problem. And more importantly, vibration analysis is capable of discovering defects before they become apparent. Thus, you will be alerted to budding equipment problems, and can allow your engineers or technicians to be ready for repairs and carry out repairs at a convenient time rather than during emergency situations.

Vibration analysis, which is done through a vibration analyzer, and some skill, can help a person pinpoint the causes of uneven and rough machinery conditions. Vibration analysis systems are really useful for modal analysis and vibration testing.

When it comes to analysis requirements, vibration analysis is complicated and requires human expertise and capability. However, it is an inexpensive and functional diagnostic tool to ensure a trouble-free machine.
