Abstract

A method 100 for detecting damage in a component of a rotary machine includes collecting, via one or more sensors 52, 54, vibration data 74 relating to the component. The method 100 also includes identifying 106 energy 86 of at least one harmonic or sideband series within the at least one region 78 indicative of a damaged component and identifying energy 88 within the at least one region 78 excluding the at least one harmonic or sideband series. Further, the method 100 includes determining 110 at least one damage ratio based on the energy 86 of at least one harmonic or sideband series within the at least one region 78 indicative of a damaged component and the energy 88 within the at least one region 78 excluding the at least one harmonic or sideband series. Moreover, the method 100 includes calculating a damage factor of the component as a function of, at least, the at least one damage ratio. In addition, the method 100 includes comparing the damage factor to a predetermined damage threshold, wherein a damage factor exceeding the predetermined damage threshold is indicative of a damaged component.
