Practical Rotor Dynamics for Users

Following a brief overview of the history of the development of key aspects of rotor dynamic technology, this paper describes ways to estimate critical speeds, and cipher them from resonances and other vibration phenomena. The influence of various bearing types on a rotor’s synchronous and non-synchronous dynamics is reviewed. Target audiences for this material are those most likely to be making and interpreting vibration measurements – in other words, machinery users and maintainers.
