If the slope is 16°, load is 100N, and slip ratio increases from 0 to 0.6, the relative errors of predicting normal force, drawbar pull and driving torque between calculation values and experimental data are less than 10%. The model can predict wheel-terrain interaction mechanics effectively for a rover while climbing up slopes.
