The method of reasonable selection of a pneumatic tire set for an agricultural tractor

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