05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
DescriptionThe article introduces a study on the creation of a simulated physical and mathematical model of the working process of a strip thrower, throwing soil in a directed flow. The problem solved with the help of this work is aimed at optimizing the cutting and ejection process in a given direction of the soil with minimal energy consumption with a maximum emission range. The article describes a methodology for calculating the milling thrower, which is oriented to the formation of the required amount of soil to create a mineralized strip at the edge of a forest bottom fire. Improving and realizing the full reproduction of physical and mathematical models using process simulations, you can save resources on the development of forestry aggregates. The study presents a productive method of processing soil with milling cutters, which helps to reduce energy consumption due to the formation of oriented mineralized flows of soil. For a physical and mathematical description of the process, a simulation program has been compiled that allows you to test the specific task of minimizing energy consumption at a maximum distance of soil discharge with a constant flow density to the rotational speed of the milling throwers

MATHEMATICAL MODELLING OF THE COMPRESSION PROCESS OF WOOD
DescriptionRheological model for wood mechanical behaviour, viewed as a medium with dual porosity, is considered. Mathematical modelling of compression process of a wooden sample in a special mould is done at stable temperature conditions with the help of numerical methods. It is shown, in particular, that the durability level of essentially depends on the rheological characteristics of the structural skeleton and the wooden substance, as well as on reallocating of fields of moisture and porosity
