МОДЕЛИРОВАНИЕ БУРОВОЙ МАШИНЫ С КОЛОННОЙ БОЛЬШОЙ ПРОТЯЖЕННОСТИ

The paper is devoted to mathematical modeling of the operation of a drilling machine with a double column of long-length pipes. Analysis of vibrational processes of internal drill string allows you to set a limit on the angle of twist of cross-section elements of the drill string, and to determine the vibrational characteristics in the transmission, and to ensure consistency of performance parameters of the Executive body and the physical- mechanical properties of the object.
