Studying of energy operation parameters of multiple elements machine-tractor units
Abstract
In article justification for a method of a research energy parameters ofmultielement aggregates functioning of machine and tractor of arbitrarystructures have been offered. Energy performance indicators of functioning of MTA have been researched. Determination direct and indirect energy costs which are directly connected with accomplishment of agricultural works has been offered. Energy assessment allows to determine direct and indirect costs of energy in case of production performance plant-growing works. It is carried out for the purpose of balance capacity determination and correctness of the choice energy means for the farm vehicle or determination of the traction characteristic for the tractor. Total energy costs when using MTA consist of direct costs of the spent combustible and live labor. Also, they consist of indirect expenses that occurs in machines and energy costs on repair and servicing of the aggregate.One of the main performance indicators of mechanized implementation processes in plant-growing is the size of energy costs for product receipt.Energy costs on engineering procedure of the main handling of the soil (plowing, a disking, a harrowing) are equal to the amount of specific energy costs on individual work operation.The total minimum energy costs of production or minimum of specific energy costs can be used on energy criterion of production efficiency of products on various technologies.The engine, transmission, engines and farm vehicles are the MTA elements. They have various structure and methods of connection, transfer and power consumption therefore they have been considered as the objects spending energy. They have the mathematical description of these losses. The most widespread methods of connection mathematical models of the MTA elements were considered: parallel connection, consecutive and connection with feedback. Energy costs for functioning according to the offered technique on the example of the John Deere 8345R tractor, the bunker for the sowing material John Deere 1910 and a seeder of John Deere 1895 have been calculated.
