ANALYSIS OF GENERAL PLOW BODY TRACTIVE RESISTANCE
Abstract
Satellite monitoring and the fuel accounting is an urgent need for normal operation of motor transport. Introduction of a system activity with use of modern satellite technologies allows to lower transportation costs, to increase efficiency of use of agricultural machinery. The authors offered algorithm for modeling of technologies of a crop transportation from combine harvesters according to transfer schemes, with use of a loading crane based on the tractor-trailer and replaceable bodies. At application of the GLONASS system combines capacity grows with increase in length of furrow, and the quantity of re-loaders of different models significantly decreases. The more powerful of a re-loader is the fewer tracks are necessary due to their capacity increases. When yield increase by 2 t/ha the need for combines and re-loaders increases irrespective of their power. Rational forms of the organization of operations enable reduction of standing time of combines, increase capacity of transportation vehicles and by that grain loss reduction owing to reduction reducing of harvest terms. The problem of optimum construction and functioning of harvest and transport complexes of the agricultural enterprises with use of replaceable adapters and navigation satellite systems of GLONASS/GPS is actual. It is of major importance to national economy. The solution of this problem will make it possible firstly to raise effectiveness of performance of harvest and transport complexes because of reduction of standing time of machines and terms of harvesting and secondly to increase loading of domestic GLONASS system essential. The system of satellite monitoring with use of GLONASS data justifies costs of its installation and operation within 3-9 months that lowers the common costs of vehicle fleet by 30 percent.
