This survey is concerned with the problem of determining the dynamic modal characteristics
(natural frequencies and associated mode shapes) of rotating beams. Modal characteristics
are of paramount importance to the design and performance evaluation of rotating beams,
and have been the subject of interest to many investigators. Accurate prediction of the
dynamic characteristics of such structures is necessary in the early stages of the design
process in order to avoid any possible conditions susceptible to resonance within the range …

A survey is presented of the research on the problem of determining the natural frequencies
and mode shapes of rotating beams. Accurate prediction of the dynamic characteristics of
such structures is necessary in the early design stages to prevent failure due to vibration.
Many simplified mathematical models with a variety of geometries and properties have been
developed to investigate rotating beams.
