A Semi-Empirical Model of the Wheel-Soil System

Abstract

The article presents a proposal of a semi-empirical model of a wheel – soil system. Measurements of the values characterizing this cooperation were carried out with the use of a measuring and test stand, consisting of the SST sensor for measuring the soil stress components and a dynamometer for measuring forces acting on the road wheel. The research was carried out on three different soils: sandy, loess and peat. Graphs showing the correlation between forces and stresses in the substrate were obtained. It was observed the influence of soil type and other parameters on the type and course of the curves in these graphs.
