The criteria for the similarity of the process of digging soil with a bulldozer blade are determined based on the use of the principles of the theory of similarity and modeling. When determining the similarity criteria, a rheological model of the process of interaction of the bulldozer blade with soil and the method of dimensional analysis were used. The processing of experimental data obtained with large-scale physical models in a criterion form made it possible to significantly reduce the time and material costs for conducting experiments. The criterion equation is valid for any change in the parameters included in the dependence that determines the force of digging the soil with a bulldozer blade. The main limitation is compliance with the equality of similarity criteria for the model and the original.
Key words: criterion / experiment / rheological model / bulldozer blade / resistance force / physical model / original
