Abstract
Mathematical and simulation models of drill bit oscillations. Method for calculating the model works elastic, electromagnetic and load torques has been developed. Simulation results of autoresonant regimes with asymmetric excitation oscillations of dynamically counter balanced drilling string on the cargo-carrying cable drill bit are represented.
