Rotor dynamics ― four open questions [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2021 Despite many years of development in the field of rotor dynamics, many issues still need to be resolved. This is due to the fact that turbomachines, even those with low output power, have a very complex design.

Modal Testing of Rotors with Fluid Interaction
International Journal of Rotating Machinery, 1995 Modal testing of rotating structures has specific aspects, and it requires a specialized approach. Classical modal testing when applied to active (rotating) structures does not provide complete results.

The rotor dynamics of reeling machinery
Applied Mathematical Modelling, 1999 Wide-faced rotors for high-speed reeling operations such as those employed in paper manufacture, printing, coating and laminating are considered, and the torsional behaviour of these units is investigated. Modeling, simulation and analysis techniques are involved enabling the prediction of the torsional vibrational signature of high-speed assemblies ...
