Rashkyvs'kyy V. Butt end working organ of trenching digs machine with the guided power parameters

Butt end working organ of trenching digs machine, is a disk on the frontal surface of which there are cutting and thrower elements. The researches, directed on the increase of efficiency of work of trenching digs machine, increase of adaptation properties of his working organ due to the change of the modes of motion of cutting elements, are resulted in dissertation. The management by the power parameters of butt end working organ consists in possibility of speed formation of power impulse on a working organ with a value and frequency necessary for the separation of element of ground from an array in accordance with the change of physical and mechanical properties of ground. During implementation of work the system of mathematical models is developed "ground is working organ - drive", which describe co-operation to the disk of butt end working organ with ground during his destruction, dynamics of trenching digs machine at the impulsive loading of his working organ, dynamics of power impulsive hydraulicdrive of trenching digs machine with a butt end working organ at formation of the directed impulse by the throttle regulation of drive hydraulic motor. Certain conformities to the law of change of power indexes of butt end working organ at the change of his mode of motion by analytical and experimental ways. Character of change of the dynamic loadings is set, that operate in the elements of trenching digs machine at the impulsive loading of working organ.
