Abstract

It has been determined that under the combined action of the main mechanisms (lifting and thrust mechanism) and implement mechanism, which are part of a gear of a power shovel, the modes of operation of lifting and thrust mechanisms of engine change significantly. It has been shown that in the process of digging, changing of operating parameters is conditioned on both shovel drag force (gravitational force of rock passing into the shovel, and friction force) and changing of the relative position of links of the implement mechanism and, thereafter, arm of force. Values of operating parameters of the main mechanisms have been determined (speed, lifting and thrust force) depending on the position of a shovel in operating zone of the excavating machine under constant values of digging resistant force and digging speed. Operating space of the excavating machine with main mechanisms with accelerated service have been detected under the shovel shift along the steeply inclined trajectories, parallel to the slope of a bench. The analysis of the degree of the main mechanisms driving gears interaction under the realization of the given energy-power parameters on the blade of shovel will make it possible to substantiate the adaptive and self-organizing system of workflow control.
