Application of multi-criteria in the selection of running systems for regional use of tractors in agriculture

Abstract

The basis of the modern machine and tractor fleet of industrial and agricultural tractors are power vehicles with tracked and wheeled operating systems of various design designs. Both of these and other energy products have both their advantages and quite significant disadvantages. The article discusses the summary parametric and factorial characteristics of wheeled and tracked power vehicles used in field and transport work in the Amur region. The criteria for the formation of their traction properties, ways to reduce slipping, reduce the load of the machine-tractor unit on the soil, and the use of agricultural machinery during waterlogging are analysed. The results of a study on the use of mobile energy means in waterlogged conditions during the cultivation of agricultural crops, where their main advantages and disadvantages are reflected, the directions of choosing an energy means for use in agricultural production technologies are substantiated. It has been established that the use of tracked power vehicles with high traction properties, when aggregated with wide-reach machines in the fields of the region, will be more effective during periods of work when there is a large precipitation. At the same time, wheel energy means will also be in demand in the natural and climatic conditions of the Amur region as the most versatile structurally suitable means for performing most agricultural field operations as part of a tractor-transport unit. In this connection, the expediency of equipping the production and industrial complex and means of mechanisation of farms and agricultural enterprises of the region with energy means with various running systems in accordance with the used and scientifically based regional system of machines and technologies is justified.
