Influence of the base motion on the dry-whip onset of an on-board rotor-journal bearing system

Résumé

In this paper, the special class of on-board rotor undergoing rotor-stator contact is under investigation. In particular, a well-known and harmful contact instability, the dry-whip phenomenon, is addressed. The aim of the paper is to present original experiments evidencing this instability being triggered by a multi-axial shock translation from the rigid rotor base. Moreover, the influence of the base motion parameters, such as the shock amplitudes, directions and time shift, on the onset of dry-whip is investigated both numerically and experimentally.
