METHOD OF ENERGY IMPACT ASSESSMENT on the soil working organs of tillers and implements

摘要

Method energy estimate impact on the soil working organs of tillers and implements, comprising measuring soil hardness, determining the specific surface area of ​​the solid phase, the specific surface of the condensed phase, the coefficient of moisture permeability, porosity and moisture capacity before and after the mechanical action on the soil working organs, characterized in that determine the potential deformability of soil, which is a ratio of the energy spent on deformation and mass transfer processes per unit mass in the soil to nkretnyh conditions of its occurrence, the formula ,,,,, A, A- mechanical energy expended on the soil respectively deformation during testing hardness before and after processing it, J.; m, m- respectively deformed mass of soil for testing hardness before and after processing kg; E, E is the Gibbs free energy, which determines the energy bonds between soil particles moving in the soil sample before and after exposure to the working organs of tillers and implements, J.; m, m-, respectively soil mass in the sample taken on the tested portion before and after the machining at the same points where the portion tested hardness, kg; P, P- efforts respectively, defined on a plot of direct proportionality OA diagram P = f (h) for testing hardness portion before and after machining, H; h, h-, respectively the depth of immersion of cylindrical ferrules hardness corresponding to the value of P and P, and also determine the diagram P = f (h), m; ρ- density of the solid phase of the soil, kg / m; n, n- respectively on the test soil porosity portion before and after the mechanical arr
