Improper aligning of shafts through couplings often leads to severe vibration problems in many rotating machines. The rotor-bearing system is modelled using higher order finite elements by considering deflection, slope, shear force, bending moment with eight degrees of freedom per node. The reaction

As a method for diagnosing faults in rotating machinery, attention is being focused on changes in the sound signals generated by bearings. This provides the advantage of making it easier to set up sensors, since sound signals can be measured at a location some distance from the housing of the bearin

In this paper, some non-linear diagnostic methods for rotating machinery are introduced and evaluated from the view of diagnostic practice. The methods are pseudo-phase portrait, singular spectrum analysis and correlation dimension. The pseudo-phase portrait is simple, easy to draw, and is sensitive
