Adaptive Hydromechanical Drilling Rig Drive

A drilling machine is presented, equipped with a hydraulic drive with self-adaptation according to the load and coordination of the kinematic and power parameters of the main movement and the movement of the working body feed. For research and design of the proposed adaptive hydraulic drive based on mathematical modeling methods, its mathematical model is proposed, developed using the foundations of the theory of volumetric stiffness of hydraulic systems. The solution of the obtained mathematical model was carried out in the software environment for dynamic modeling of technical systems SimInTech. As a result, general dependences of the functional parameters of the adaptive system on the design parameters and technological conditions of its functioning were obtained. The solution of the mathematical model of the adaptive hydraulic drive shows the fundamental possibility of implementing the principle of self-adaptation by load, with external and internal disturbing influences during operation. The results obtained can be used in the design of adaptive systems of technological equipment for various purposes.
