Geometric modeling of disc furrow profile

Abstract

The provision of sufficient quantities of food products for the population of our planet is currently an urgent global problem. One of the main approaches to successfully solving these critical issues is to improve agriculture and its technical tools, particularly tillage discs. The latter’s popularity is due to modern progressive trends in minimal tillage. Compared to plows, discs significantly reduce energy costs, contribute to soil moisture preservation, and improve anti-erosion factors. In this regard, integrated CAD/CAM/CAE/PLM systems are productive tools for practically implementing the described tasks. However, their effective functioning is impossible without developing appropriate mathematical models. This scientific publication is devoted to solving such a problem by creating an analytical geometric apparatus for forming furrow profiles depending on available diameters and installation angles of tillage discs. Simultaneously, the current trends in the construction of agricultural machinery regarding the placement of disc working bodies on individual risers with the regulation of required angles of attack and deviations from vertical were considered. The developed mathematical calculations were illustrated by corresponding graphic images of furrow profiles for specific values of indicated quantities. This research also outlines promising directions for further research on the topic under consideration. Overall, the article aims to solve the problems using the integrated processing of structural and functional parameters and characteristics for agricultural discs.
