Analysis of tractive performance of agricultural tractor tire using finite element method

We established the method with finite element analysis of the running tire using an anisotropic elastic wheel model that includes the vertical and horizontal rigidities and inspected it about validity by the experimental results of the running performance and the contact pressure distribution for different inflation pressures. The contact normal stress was greater in the front half of the ground. It was a flat distribution in the vicinity of the maximum value. The running resistance and the contact load obtained by integrating measurement results of contact normal stress are almost equals to the results of calculation by drawbar pull and torque. The calculated coefficients of net traction for the experimental conditions were in good agreement with the experimentally determined values.
