Summary: A wave model of torsional autovibrations of homogeneous drill string is elaborated in the form of a torsional pendulum. The computer simulation of non-stationary torsion motions of the drill string bits is performed for the cases of the drill string rotations with accelerations. They simulate the effects of the drill string accelerating.

Key words: Drill string, bit, torsional autovibrations.
