What Is A Vibration Analyzer?
When testing for vibration in the industrial industry on processing machinery, the technicians do this with a vibration analyzer. The vibration analyzer is used for vibration testing and modal analysis.
There are two types of vibration. They are forced and resonant. Internal generated forces, imbalances, external loads, or ambient excitation are all reasons for forced vibration. A vibration analyzer receives signals in high frequency areas along with single frequencies. The vibration analyzer depends on stable recordings and make sure that the measured frequencies are correct.
A vibration analyzer uses several different types of methods for testing. There is modal analysis which is used as a stand alone technique that enhances the accuracy of the finite element analysis. The shaker testing vibration with the vibration analyzer is used to determine the component performance under vibration or shock loads.
Other uses of the vibration analyzer are to verify product designs, measure the structural fatigue of a certain material. Some will simulate the shock and vibration conditions in aerospace, transportation, or other demanding environments. The vibration analyzer is used to diagnose faults in equipment through the measurement that the equipment has inside. The vibration analyzer is mostly used in large rotating equipment such as turbines, centrifugal pumps, motors, and gearboxes. All mechanical machinery forms some sort of vibration when they are running. The vibration analyzer can diagnose this vibration to make sure that it is the proper vibration that the machinery is suppose to have. For example, it is very similar to an owner and their car. When you are driving and there are noises and vibrations that you feel and you know these are normal for your car. But you get in your car once day and there is any extra beat in that vibration of the car. It's that extra beat that tells you there might be something wrong. You, in a sense, are the cars vibration analyzer. The large machinery in today's work force all have their signature vibration which is the one they are suppose to have. But the workers are not as intimate with these machines as a person is who is driving their car so they need the vibration analyzer to pick up on those extra beats that the workers who operate them cannot. The vibration analyzer usually is run over a long period of time so the performance of the machinery can have a log of its working times, breakdowns, trouble spots, or even error free run time. This database of logs is what will be able to be compared with the vibration analyzer when it detects that extra unwanted beat.
