Three-directional contact stress distributions for a pneumatic tractor tire in soft soil
Three-directional contact stresses were investigated at three locations on a lug of a pneumatic tractor tire in a completely soft rotary-tilled soil overlying a hardpan about 250 mm below the surface. The 12.4R28 pneumatic tractor drive tire was operated at two dynamic loads and two inflation pressures at 20% slip. Three transducers were embedded in the lug face near the tire centerline, approximately the center of the lug, and near the outside edge of the lug. The general trend of stress distributions reflected the effect of tire inflation pressure more than dynamic load in this experiment. Increased dynamic load increased the levels of stresses. The maximum normal stress occurred near the tire centerline at high inflation pressure. The maximum tangential stress occurred near the tire centerline and decreased as the position moved from the tire centerline to the edge of the tire. At the high inflation pressure, the maximum lateral stress was concentrated near the bottom center position for each transducer.
