Predicting Critical Speeds in Rotordynamics: A New Method

Conference Journal of Physics Conference Series · October 3, 2016 In rotordynamics, it is often important to be able to predict critical speeds. The passage through resonance is generally difficult to model. Rotating shafts with a disk are analyzed in this study, and experiments are conducted with one and two disks on a ... Full text Cite

Nonlinear dynamic simulation of an active magnetic bearing system with non-symmetric coordinate coupling forces

Conference American Society of Mechanical Engineers Paper · December 1, 1997 Equations of motion are presented for a two degree of freedom system representing a rotor suspended with an active magnetic bearing. The rotor is subjected to both a rotating unbalance force and a steady load, which is balanced by differential bias in the ... Cite
