Abstract
A method is provided for analyzing vibrations of a variable speed rotating body. The method includes producing a signal that is proportional to an acceleration of the rotating body and producing a plurality of pulses. Each pulse represents a revolution of the rotating body and is indicative of a vibration sample at a rotational position of the rotating body. The signal is converted to a numeric value that is indicative of a vibrational amplitude of the rotating body. The plurality of pulses are converted to revolution time periods indicative of a rotational rate of the rotating body. The method also includes producing a harmonic vibrational amplitude at a harmonic of the rotational rate of the rotating body, and representing a phase of the harmonic vibrational amplitude relative to the rotational position of the rotating body.
