- W4362553337 abstract "BACKGROUND: The method of reasonable selection of an agricultural tractor tire set is a tool to compare and choose a tire set with the best properties, to analyze the features of tire-soil interaction, to evaluate the feasibility of installing the proposed tire set and to identify ways of tractor design improvement. The relevance of tire set optimal selection for vehicles operating in agriculture is related to the soil compaction by chassis that lead to a change of its structure and agricultural yield reduction. In addition, it is related to low traction properties which increases fuel consumption, reduces performance and accelerate tire wear during operation on soft soils with wheel slip.
 AIMS: The aim of the study is to increase the operation efficiency of an agriculture tractor as part of a machine-tractor unit with the pneumatic tire set selected with the developed method. The research subject is the influence of tire design properties on the tractor operational indicators.
 METHODS: The article presents the method that allows to choose pneumatic tires from a wide range of different models and manufactures according to known and available technical properties for a newly-developed or modified agricultural tractor. A specific feature of method is determination of a generalized parameter of tractor operation and using it for comparison of different tires instead of using individual indicators. Driving wheels pneumatic tires of different sizes and properties for a four-wheel drive general purpose tractor are used in calculation. The method includes analytical determination of agrotechnical, technical, technical-and-economic operational indicators of tractor as well as economic components such as: maximum pressure on soil; a transverse static stability angle of a tractor, a slipping ratio, tire set cost. According to the calculated indicators and tire set cost, a generalized parameter is determined with the Harrington method and used for selection of pneumatic tire set.
 RESULTS: As a result of the method application, tire sets for the K-7M Kirovets agricultural tractor were determined such as: the 710/70R42 tires regarding the main operational indicators of the tractor and the 710/70R38 tires regarding the main operational indicators of the tractor and tire set cost.
 CONCLUSIONS: The given method can be proposed to tractor manufactures for tire set selection, chassis evaluation and identification of ways of design improvement." @default.
