Researchers from the Kazan State Agrarian University, in collaboration with the Tupolev Kazan National Research Technical University (KNRTU-KAI) and the Institute of Mechanics and Mechanical Engineering of the Kazan Scientific Center of the Russian Academy of Sciences, have developed mathematical models to determine the optimal operating modes of tractors for various soil types. Their development could lead to fuel savings of up to 30% when performing maneuvers.
We have established quantitative relationships between soil properties and tractor operating modes. The obtained relationships allow us to assess the impact of soil agrophysical properties on the energy efficiency of units and can be used in the development of automated control systems for agricultural machinery.
During field tests, specialists studied the operation of tractors on three main agricultural backgrounds of the Middle Volga region: compacted plowing, freshly plowed field, and stubble. Optimal loads were calculated for each soil type: 6.9 kilonewtons for compacted plowing, 6.6 kilonewtons for freshly plowed field, and 5.9 kilonewtons for stubble.
Doctor of Technical Sciences, leading researcher at the Institute of Mechanics and Mechanical Engineering of the Federal Research Center of the Kazan Scientific Center of the Russian Academy of Sciences, Vladimir Fedyaev, stated that the introduction of automated tractor control systems with sensors that determine the type of soil will allow the equipment to automatically select the most economical and efficient operating mode.
