Kolesnik I. Effectiveness increase of technical state control of tractor steering in transport works

The main scientific result of the dissertation is the development of theoretical bases and methodological principles for improving the efficiency of control of the technical state of the tractor's steering control on transport works. The proposed index of tractor's assessment of transport operations is a transfer function of angular accelerations of steering wheels and a helm which allows to evaluate its functioning without interfering within the construction or stopping of the transport process. An express method for assessing the technical condition of the hydraulic power steering of the tractor and its components without dismantling was developed. Experimental studies of stability of tractor's traffic on transport works and the complexity of diagnosing of hydrostatic steering control of tractor on the basis of the justified express method have been carried out.
