Vibroprotective device is created for regulation of dynamics of the drilling string by means of both accumulation and redistribution of the energy of longitudinal-torsional vibrations. Mathematical model of the device operation is proposed, and features of the calculation of planetary roller-screw mechanism are considered.

Key words: steel drilling pipes, longitudinal-torsional vibrations, drill regulator, planetary roller-screw mechanism, mathematical model.
