This article informs us about testing the theoretical dependence to calculate cone index re-garding the soil deformation module. Common methods of calculation tractive performance of wheeled mover do not allow to analyze the influence of the geometric parameters of wheeled mover,inner tire pressure, slip ratio, wheel load, as well as the physical and mechanical properties of forest soil on rolling resistance, net thrust and drawbar pull coefficient in complex.
cone index, forest soil, deformation modulus, physical and mechanical properties of forest soil
