Operational substantiation of zonal recommendations for the efficient use of machine-tractor units (MTU) in the conditions of the KBR

The article proposes a fairly simple method for solving aggregation problems using only typical regulatory and reference information. Based on this method, it is possible to quickly develop relevant recommendations even before the start of wide industrial operation of new tractors. At the first stage, a study is carried out using the example of traction units, the most common and complex in terms of their assembly. The proposed methodology is simplified by sequentially studying the MTA on two mathematical models. The first model characterizes the functioning of the unit in these natural production conditions. For this model, a mathematical expression of the optimality criterion is compiled and the corresponding tractor power is determined, which can be realized with the greatest efficiency. Taking into account the features of the technological process in the specified conditions, the type and specific brand of the tractor are selected. The second model is characterized by the interaction of the tractor mover with the soil and the working bodies of the implement with the processed environment during the working stroke of the unit. This model, taking into account agrotechnical requirements, allows determining the values of capture width and speed, at which the specific net productivity (per unit of power) will be the highest or energy costs will be the lowest. The methodology was tested using the example of substantiating a plowing unit for the conditions of the Kabardino-Balkarian Republic. The proposed methodology allows developing recommendations for the effective use of units in specific working conditions in a visual and accessible form.
