INFLUENCE OF TIRE INFLATION PRESSURE AND WHEEL LOAD ON THE FOOTPRINT BETWEEN SOIL AND TIRE
Journal Title: ISB-INMA TEH AGRICULTURAL AND MECHANICAL ENGINEERING - Year 2017, Vol 0, Issue 1
Abstract
Shape and size of the footprint and, thus the depth at which stresses are transmitted into the soil are influenced by wheel load and tire inflation pressure. A mesh - type sensor was used for measuring the contact pressure in the footprints corresponding to five tire inflation pressures and five wheel loads. For each test were obtained the 2D maps showing the shape of footprint and also the distribution of pressure at soiltire interface. It was found that at minimum tire inflation pressure the shape of footprint tends to be rectangular and, by increasing tire inflation pressure to the maximum, the footprint has rather elliptical shape.
