DETERMINATION OF THE EFFICIENCY OF ARABLE UNITS AT DIFFERENT MODES OF POWER TRANSMISSION FROM A TRACTOR ENGINE TO A WORKING MACHINE
The formula for determination of the efficiency of ploughes is derived and presented. The complete efficiency of a plough is divided into the technological one, which characterizes the energy perfection of working elements; the mechanical one, which characterizes the perfection of plough design, and the agricultural one, which determines a degree of coincidence of the obtained ploughing quality to the one required of field management. To determine the efficiency of an arable unit, the graph theory is used, which presents a unit in the form of a signal graph depending on a way of realizing the engine power. The method of determining the efficiency of a plough and that of a unit as a whole are described. The developed method allows one to determine the efficiency structure of an arable unit and machine, to find energy losses, and to solve the problems on improving the design of arable units on the scientific grounds.
