Essay

The thesis is devoted to the reduction of dynamic loads of rotary drilling rigs equipment through the effective damping of longitudinal vibrations of drilling rod. Dynamic simulation of systems of dynamic loads reduction of rotary drilling rigs was carried out. A mathematical model describing the motion of the elements of the model was developed. The comparison of the calculated and experimental spectra was carried out and the adequacy of the accepted modeling method was verified. Autonomous system of electric drive vibration isolation which also plays the role of a dynamic vibration damper of mounting group was developed. Industry - mining machines (engineering sciences).
