Severity analysis apparatus and method for shafts of rotating machinery

Severity analysis apparatus and method for shafts of rotating machinery

A method includes receiving (402) one or more vibration signals representing physical vibrations generated by a shaft (104) of a machine (106) during operation. The method also includes determining (404) a rotational speed of the shaft. The method further includes identifying (406) one or more sets...

description A method includes receiving (402) one or more vibration signals representing physical vibrations generated by a shaft (104) of a machine (106) during operation. The method also includes determining (404) a rotational speed of the shaft. The method further includes identifying (406) one or more sets of frequency components of the vibration signals based on the speed of the shaft, where each set of frequency components is associated with an operational characteristic of the shaft. In addition, the method includes determining (408) one or more health indicators of the shaft based on relative energy levels of the frequency components in each set of frequency components.
