Abstract

A brief overview of the types and properties of working equipment of a crawler bulldozer is presented. Methods for determining the forces of resistance to digging the ground with a bulldozer blade are analyzed. Disadvantages of existing methods in determining the values of the forces of resistance to digging, difficulties in calculating their values, which in practice represent an oscillatory process, are noted. A digital model of the working equipment of a bulldozer is proposed, based on the theory of layer-by-layer soil development, which allows calculating the minimum and maximum values of the digging resistance forces depending on the parameters of the soil and the blade when the drawing prism is increased.
