Abstract
In order to comply with agrotechnical requirements and reduce fuel consumption when performing tillage operations, various methods of controlling the depth of plowing are used: position, draft, height and mixed. The choice of the method is carried out subjectively by the operator in the presence of appropriate technical means and visual assessment of the results of the work, therefore, substantiation of the rational controlling method is an urgent task. The results of theoretical studies of the process of controlling the depth of tillage by the working bodies of the plowing unit are given. Taking into account the elastic and damping properties of tires, the parameters of power wiring, as well as the compressibility of the working fluid in the nodes of the hydraulic system and the pliability of pipelines, a mathematical description of the process of functioning of the plowing unit equipped with an electrohydraulic drive of the attachment is compiled. Using mathematical modelling with force and kinematic disturbances from the soil, comparative statistical estimates are obtained on the accuracy of the tillage depth and energy consumption for the control process with various methods of regulation. Based on the numerical implementations of the model for the given conditions of the agrophone, a rational method of regulation is determined which satisfies the specified requirements. It is noted that with the altitude-force method of control, the smallest deviation of the tillage depth from the specified one is achieved with a decrease in energy consumption in comparison with the power method by 1.2 times.
