This paper analyses a control mechanism designed to signiยฎcantly ameliorate the sustained excitation of torsional relaxation oscillations (slipยฑstick) due to frictional torques generated by an active bit during drilling operations with an extended drill-string.

An analytical method for the vibration analysis of unidirectional and multibranched torsional systems is investigated. In the study, an alternative power-ยฏow graph model and the model operation technology are introduced for constructing the analytical graph model of the torsional system, including i
