Abstract

Tire-soil relationship is an important research topic in terramechanics. In this paper, a tire-soil interaction model considering soil cohesion is established based on discrete element method (DEM). Through the coupling of EDEM and RecurDyn, the traction characteristics of tire under different slip ratio and the same load were studied, and the microscopic behavior of the particles was analyzed. The results show that with the slip ratio increasing from 0% to 75%, the value of the drawbar pull increase from about -1000N to about 2000N and the relative motion of particles becomes more and more violent.
