Frequency response functions and modal parameters of a rotating system exhibiting rotating damping [PDF]

open access: yes, 2014
In the analysis of the stability threshold speed caused by rotating damping in rotating machinery, there is a lack of experimental data. This stability threshold speed can be found theoretically by means of a linear speed dependent model. The accuracy of
