The methodology for experimental studies and the analysis of the obtained results intended to determine the analytical dependencies and numerical values of the coefficients in a mathematical model of the contact interaction of working body of digging machine with a frozen soil are presented. Modeling of the process was aimed to take into account the physical and mechanical properties of the frozen soils and to determine a nonlinear behavior of the stress distribution over the contact surface of working body. As a result of the research, the main principles of the processes were revealed, which allowed one to validate both the design parameters of the working bodies and the technological parameters of the frozen soil excavation by digging machines.
Keywords: frozen soil, working body, digging machine, strength, energy intensity.
