Vibration analysis as an important

Vibration analysis as an important analysis method of rotating machinery gear fracture [11], has been promoted and applied in industrial and mining enterprises, especially through vibration spectrum analysis, the cause of failure has been accepted by most field technology. But many people tend to ignore it when they analyze the time-domain waveform. They think it is difficult to find the root of the fault from the time-domain waveform. The importance of time-domain waveform analysis is illustrated by a typical practical case.Vibration analysis, first of all, through the data collector to collect vibration signals, and usually obtain the original data in the form of time waveform, time waveform intuitive and easy to understand, for some with obvious fault signal waveform characteristics, so you can use waveform analysis, the first time the imbalance occurs, the most obvious impact on the wrong time-domain waveform.
