Analysis of the dry whirl and dry whip response in a vertical active magnetic bearing drop test rig
TL;DR: In this article , theoretical research based on a rotor-TDB model system is developed in order to predict the dynamic response of a vertical rotor drop failure, and the effectiveness of this model is validated by an AMB-tended touchdown bearing (TDB) rotor experiment.
