Abstract
A system for determining a shaft misalignment in a turbomachinary train having a plurality of components with serially coupled rotating shafts. A disclosed system includes a sensor affixed to a component of the turbomachinary train proximate a rotating shaft, wherein the sensor collects vibration data along an axial direction of the rotating shaft. Also provided is a frequency analyzer for generating frequency domain data from the vibration data and an analysis system for analyzing a frequency component of the frequency domain data at one times a rotational frequency of the rotating shaft to identify a misalignment between the rotating shaft and an adjacently coupled rotating shaft.
