Despite the promising potential of hybrid electric power-split layout, its broader market penetration is prevented by large number feasible solutions and constructive complexity, which overcomplicate design process. Moreover, due to lack relevant literature references, transmissions even more difficult if concerning applications outside automotive agricultural sectors. In this paper, a general ...

The late detection of the kick (the entrance of underground fluids into oil wells) leads to oil well blowouts. It causes human life loss and imposes a great deal of expenses on the petroleum industry. This paper presents the application of adaptive neuro-fuzzy inference system designed for an earlier kick detection using measurable drilling parameters. In order to generate the initial fuzzy inf...

Abstract The work is devoted to the study of an adaptive hydraulic drive for tool feed a mobile drilling rig. analysis ways regulation considered systems carried out, criteria and parameters their functioning are determined. As result analysis, original circuit design was applied, where fed using adjustable volumetric motor with control loop, taking into account changing load on during drilling...
