Calculation of a track formation process during wheel-ground interaction

Abstract

The article provides the mathematical model of formation of a track depth depending on the size of vertical loading of a machine-tractor unit wheel, the structural parameters of the wheel and the soil properties. Based on the developed mathematical model, the experimental data of wheel-soil interaction and the soil properties, the track formation process in the soil depending on the pressure created by the wheel in a zone of contact with soil is proved. The analysis of the process of forming the track allows us to conclude that the intensity of track formation decreases with the increase in the wheel-ground interaction time.
