The Influence of Changes in the Vertical Acceleration of Tractor Unit on Soil Compaction during Field Operations

Abstract

The article deals with the influence of fluctuations in vertical accelerations on soil compaction as a process of change in soil consistency under the influence of high mechanical loads, namely, heavy farm machines. The main object of this research is to investigate the pressure change in topsoil and to devise recommendations for the reduction of soil compaction resulting from intensive vertical accelerations during the movement of a field machine. A computational and experimental method of determining soil strain and mechanical stress caused by a wheel, taking into account soil properties and the value of the vertical acceleration components, has been proposed.
