Essay

The dissertation is devoted to the mathematical models and dynamical processes calculation algorithms developing, which appear in drilling rigs at the braking time of the drill pipes string and creation of the dynamical forces in rigs elements decreasing ways and borehole drilling effectivity increasing. The brake modes of the drill rigs work is investigated. Practical recommendations for calculation, construction and expluatation of drill rigs is created.
