Abstract:

Abstract The paper is focused on the issues of controllability of machine-tractor units based on wheel-type tractors during their non-straight driving on the soil surface, which is positioned at an angle to the horizon. There were obtained analytical expressions for the determination of the actual indicator of control λd, including both the power and the design parameters of the machine-tractor unit, which affect the abovementioned indicator in the longitudinal vertical plane. These expressions are obtained for the tractor driving on both road and also driving during field operation. In additi

One of the main indicators of internal combustion engines, tractors and the machine-tractor unit as a whole it's the power. It can change in the process of operation and there comes a time when subsequent use is inadmissible or inexpedient.

Abstract:

Abstract Modern sowing machine-tractor units (MTU) can be divided into single-machine (single-module), two-machine (double-module), and three-machine (triple-module). The firsts, consisting of a tractor and a trailed/mounted seeder, are the most studied and, therefore, the most widespread. Two-module MTUs mainly use trailed or semi-mounted hitch and trailed seeders. The units of this type have been studied less. Three-module sowing complexes are even less common. Most are based on a trailed hitch and trailed seeders placed behind the tractor. There are samples of MTU with side-mounted seeding

Abstract:

The discrepancy between the working width of the plow and the width of the tractor leads to asymmetry of the arable units. The geometry of the share surface of the reversible plow contributes to the generation of lateral forces on the working tool. All this contributes to the imbalance of the working body and the deviation of the tractor from straight-line movement during plowing. To maintain a straight line, the driver has to correct the vehicle movement every 5-10 meters, which makes him more tired. To study the causes of lateral slip of the plowing unit, a mathematical model was built. It c

When completing machine-tractor aggregates (MTA), the question becomes how to choose a farm machine to a tractor in order to obtain higher productivity of the unit with less fuel consumption and ensure the reliable operation of the tractor engine. Research by many scientists has shown a lot of criteria or methods for determining the load level of tractor engines when performing fieldwork. They recommended the coefficient of permissible and possible overload of the engi

Abstract:

Tractor traction properties depend on many factors including engine power, operating weight and tractor weight distribution across axles, dimensions, profile, gears range and gear count in the gearbox. Moreover, the tractor technical condition plays a vital role, encompassing aspects from the fuel system affecting the engine power output, to the chassis, influencing terrain traversability, maneuverability, and soil deformation.

Abstract:

Abstract Recently, rapid development of controlled traffic farming convincingly demonstrates the broad prospects of using the wide span tractor-based field machines throughout the world. The issue at hand lies in the fact that having a wide span tractor-based machine with steering-wheel system moving along the tracks of a constant technological track is not a rational option. According to the concept of bridge and rutting agriculture, it is advisable to subordinate the automated means of mechanization to the principles of the functioning of the coordinate transport system in which machines can

Abstract:

Аdvantages and disadvantages of various types of fuels are considered in the article; the method of cleaning alternative fuel for agricultural machines is developed, namely, the increase of methane content in the fuel mixture of diesel - gas as an alternative fuel for machine - tractor aggregates. The proposed method results in relatively small losses of methane to 0.06%. When the system operates at standard pressure, power consumption is less than 0.04 kWh / m3, which gives the system the ability to work economically. The fuel gas produced as a by-product can be good for heating a bioreactor.

The analysis of the influence of unsteady load on the engine performance of the machine-tractor unit (MTU) is given. Theoretical studies are presented to determine the effective performance of the MTU engine under unsteady load and their comparative analysis with the results of experimental data. This is necessary to verify the adequacy of theoretical dependencies with the results of experimental studies.

The research aim is to experimentally determine the parameters of the adaptive support of the power unit of the machine-tractor unit. The need to use adaptive supports for power plants of machine-tractor units is due to a change in their speed and load modes of operation in a wide range. The currently used supports have constant parameters, which are determined, as a rule, by statistical characteristics and characteristics of the nominal operating mode. Reducing the negative impact of vibration on the efficient performance of the power plant is proposed by creating supports with adjustable cha
