Vibrational processes of the cone drilling machine at different rotation modes of the drilling rig. Research subject. Parameters of drilling rig rotation related to transverse vibrations. Purpose. To increase the drilling productivity of a cone drilling machine by substantiating the rational parameters of drilling rig rotation. To achieve this goal, the following research objectives were set: - to study the operating modes of the cone drilling machine in order to effectively control the oscillations of the drilling rig and the complete elimination of extreme loads on the machine components and the driver's workplace; - to determine the possibility of stable operation of heavy drilling rigs up to 24 m long, taking into account the centrifugal force arising from the rotation of the curved axial drilling rig, at a rational number of revolutions without the appearance of extreme modes of rotation; - to determine the rational operating parameters of the drilling rig rotation in order to increase the drilling speed and ensure the resonant mode of operation of the machine; - to develop effective methods and systems for damping transverse oscillations of the drilling rig.
