Vibration Analysis

Frequency analysis is the analytical method most often used for fault identification in operating machines, for example during regular operation, start-up and coast-down or during tests and experiments.

 

Any time when

• faults or the cause of damage are to be identified,
• damaged components are being identified,
• the degree of damage is being determined,
• timely recognition of on-going damage is necessary,
• the progress of existing damage is to be monitored or
• quality acceptance of an entire machine is made after installation or repair

 

A frequency, or phase analysis, can provide the necessary basis for a solution.

 

Vibration Analysis can detect the following

• Unbalance
• Misalignment
• Eccentricity
• Bent Shaft
• Shaft Crack
• Mechanical looseness
• Journal Bearing Faults
• Rolling Element Bearing Faults
• Rotor Rub
• Cavitation
• Electrical Motor Problems
• Gear Faults
