Modeling the process of strain and motion of the soil in a subsoiler operation area

Analysis of available literature shows that nowadays an advanced scheme of the technological process and new designs of operating elements of the subsoiler working in conditions of deblocked cutting has been developed. The aim is to improve the quality and to reduce the energy consumption by machines and equipment during deep tillage. However, at present, the theory of vibrations and strength loading of the units of subsoiler, when its operating elements interact with soil, is not sufficiently developed. This paper highlights the issues regarding the modeling of soil during interaction with operating elements of a subsoiler. Based on the use of the Rakhmatulin model of a compressible plastic medium and the Ilyushin «flat cross-section hypotheses», the equation of the soil motion is formulated, and the dynamic phenomena occurring in the soil and subsoiler elements under variable traction are described. The calculation results are obtained in the Maple-8 programming environment using the methods of solid mechanics and soil mechanics.
