Abstract

Throughout the present study, a simulation of tire–soil interaction model was considered with special view at the two-Dimensional (2-D) FINITE ELEMENT METHOD (FEM) model of carcass. In contrast with the existing 2-D tire models, in the new model it was not tried to find a mathematical description for the global reaction of tires, but was based on a mechanical structure of the basic components of a tire. Here, the reproduction of the carcass as the most challenging part for a 2-D model was described in details. Also, the reproductions of tire wall model as a HYPERELASTIC material and soil model as an ELASTOPELASTIC one were investigated. Coefficients of mechanical behavior of silty-loam soil were accurately assessed to obtain an effective simulation. The results of simulation implemented in MATLAB7 Software, showed that the radial-ply tire benefitted from a greater tractive efficiency than the bias one within the same conditions on silty-loam soil. Bias-ply tires suffered from a greater motion reduction (slip) and while their gross traction was slightly greater than that of radial-ply tire. The net traction force was estimated as the same for both tires. Also, the results of simulation and tests revealed that the radial-ply tire bore lower rolling resistance than bias-ply tire on silty-loam soil in similar conditions. Based upon the simulation results, the effects of slip, inflation pressure and mechanical stiffness of soil on tractive efficiency were satisfactorily predicted.
