Abstract
Recently, much attention has been paid to intensification processes in many sectors of the economy and mechanical engineering. In addition to the intensification of production processes, attention and intensification of processes of interaction between working bodies and destroyed environments are not overlooked. Intensification of working processes in the design of working environments represented by soils is due to shock, vibration, vibration and high-speed loading of the working environment. In this case, the soil undergoes complicated deformation processes that occur with different energy transformations, which is transmitted to the soil from the working bodies of technical systems of soil-destroying machines. When deforming and destroying the working media, the latter exhibit elastic, plastic and viscous properties. In addition, in addition to internal movement in working environments, external friction processes occur between the cutting elements and the soil. Working environments consist of soils, which in general have a three-phase structure, the feature of which is that, in addition to solid particles of soil in its volume are water, saline solutions and gas. Two methods of mathematical modeling are used to describe the processes of formation of energy flows and their transformation in the destruction of soils. For the first method, when describing processes, methods are used based on the application of the theory of elasticity and plasticity of continuous media. The second method is based on the application of phenomenological mechanorheological models. Due to the fact that the processes of dynamic destruction of the working medium occur in space and time, the mechano-reliance model of high-speed destruction of working media should describe changes in the nature of deformations and stresses at each contact point of the cutting element with the soil, as well as the quantitative and qualitative dependence of the stress-strain state on the load speed and time the process of deforming the working environment.
