Summary: A mathematical technique is developed to describe the interaction process between a forest disk plow and soil medium when fire mineralized breaks are developed. Disk plowing provides insufficient quality of a furrow slice rotation therefore it is recommended to equip spherical disks with additional breasts of a plow-bottom type. To determine the optimal parameters of the developed design, the interaction of the working organ with the soil medium is simulated using the finite element method, where the soil and the spherical disk are represented as a set of a large number of separate spherical elements interacting in a certain way. The authors describe the technique of composing the equation of plane to simulate the operation of a plow-bottom breast. A special singling algorithm is used for uniform distribution of spherical elements, when the number of initially created points is larger than required, and the points located in dense areas are eventually removed. A computer program was developed to implement the mathematical model in the form of a system of differential equations and to conduct theoretical experiments. In the course of the computer experiment the disc with the fixed parameters moved linearly for a certain distance and the configuration of the developed furrow and the quality of soil cultivation and the energy capacity of the process were evaluated. |
