Abstract

Abstract: The algorithm is the basis for creating a computer program to calculate and forecast the allowable travel speed (maximum and minimum) of innovative dynamic tillage tools attached to relevant implements. The source data for calculation were soil hardness, the coefficient of terra-dynamic resistance and the specific tractive resistance per unit of the active frontal area of an innovative dynamic tillage tool. The limitations, which were set by the agro-technical requirements to the surface tillage, were the uneven tillage depth, the roughness of the field surface, the ridges on the field surface after the tillage, and the soil loosening degree. The study aimed to design an algorithm and its generalized block diagram for determining and forecasting the allowable travel speed of an innovative dynamic tillage tool in various operational conditions. The study object was an arrow-shaped innovative dynamic tillage tool with the working width of 330 mm designed for the surface soil tillage to the depth of up to 14 cm. The study subject was a calculation algorithm for parameters and indicators that affect the allowable travel speed of a dynamic tillage tool. The study applied the methods of mathematical modelling and experimental investigations for the energy assessment of soil tillage tools. The scientific novelty of research is an algorithm and its generalized block diagram for calculating and forecasting the allowable travel speed of a dynamic tillage tool. The paper presents the procedure for calculating the parameters that have a significant effect on the allowable travel speed of a tillage tool.
