Drillstring vibration is one of the major causes for a deteriorated drilling performance. Field experience revealed that it is crucial to understand the complex vibrational mechanisms experienced by a drilling system in order to better control its functional operation and improve its performance.

In this paper the variable mass rotor/fluid system is considered. A rotor with variable mass is settled in hydrodynamic bearings. The dynamic properties of the rotor on which the fluid force and the impact force (due to mass variation) act are analyzed. The conditions of stable rotation are obtained
