1. A system for determining a shaft misalignment in a train of components with serially coupled rotating shafts, comprising:

  • a sensor affixed to a component of the train proximate a rotating shaft, wherein the sensor collects vibration data along an axial direction of the rotating shaft;

    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.
