WebMay 19, 2016 · The machine generates “low frequency” vibration related to unbalance, misalignment, looseness and other common faults. It also generates “high frequency” vibration related to gear mesh, lubrication problems, bearing faults, and other faults. WebIt also introduces the time waveform and how it is converted into a vibration spectrum. The relationships between acceleration, velocity, and displacement are illustrated, as well as their direct relation to machine wear, fatigue, and failure. The true meaning of Overall Vibration is also given here, along with how it is measured.
