Abstract

When the moist soil is excavated, the soil sticking and freezing to the working units of the earth-moving machines take place. It is the phenomenon that considerably reduces the plant`s efficiency. There are four main groups of methods intended for eliminating adhesion of soil to the surface of the working bodies of earth-moving machines. As for the nature and the operating effects of the methods, they can be divided into the preventive methods and the means ones for cleaning the working units of the earth-moving machines. On the special shear stand, the multifactorial test has been conducted using mathematical theory of experiment to determine the practical effect of antiicing liquid usage as a preventive method when the intermediate layer is used in the contact point "soil-to-working units" to reduce adhesion to metal surfaces soil machines. Mathematical processing of the obtained results was carried out using the MODEL program for multifactor dependencies using the least squares method. As a result of the processing of experimental data, regression equations were obtained without the action of the lubricant and with the use of anti-icing fluids "MAXFLIGHT 04" and "OCTAFLO EG". Multifactorial dependences of shear stress are obtained. To interpret the results obtained, quasi-onefactor dependences are given for fixed values of two factors among three, the response surfaces for quasi-one-factor dependencies for anti-icing fluids of the brands MAXFLIGTH 04 and OCTAFLO EG are constructed. Analysis of these dependencies in the investigated range of factor changes shows that the use of anti-icing fluids of the brands MAXFLIGTH 04 and OCTAFLO EG reduces the shear stress to 60%.
