  • Vibration Due To Shaft Misalignment

    Vibration Due To Shaft Misalignment

    Oct 21, 2009· Unlike imbalance, misalignment does not produce forces that are similar in the radius of the machine. Vibration in one radial direction may be very different in amplitude when compared to vibration in another radial direction. This is one instance where amplitude readings are not only helpful in detecting a problem but also helpful in diagnosing a problem.

    Phase Analysis: Making Vibration Analysis Easier

    In vibration analysis, phase is measured using absolute or relative techniques. Absolute phase is measured with one sensor and one tachometer referencing a mark on the rotating shaft (Figure 3). At each measurement point, the analyzer calculates the time between the tachometer trigger and the next positive waveform peak vibration.
