COMPARATIVE ANALYSIS OF SOME TIRE DEFORMATION MODELS USED FOR THE PREDICTION OF TRACTION CHARACTERISTICS
Journal Title: ISB-INMA TEH AGRICULTURAL AND MECHANICAL ENGINEERING - Year 2017, Vol 0, Issue 1
Abstract
In the present paper is presented an interaction tire-soil model, taking into account of the deformation of the tire section under load. The tire section is considered to be elliptical; under load the minor axis decreases, while the major axis increases. The equations of the traction model were incorporated in a computer program; the length, width and area of the contact patch, the traction force and traction efficiency are calculated for each value of the wheel slip. Field tests were performed in order to validate the model; the experimental data were collected during plowing tests. In order to evaluate the precision of the model the predicted data were compared with the test data by the means of a goodness-of-fit analysis.
