Boldovskiy V. Evaluation of tractive wheeled vehicle propelling agent impact upon soil

Object of research is the process of impact of propulsion devices of wheeled traction vehicles on soil. Subject of research is impact of running systems of wheeled traction vehicles on soil physical property change. Analytical, numerical and experimental methods of researches that are bases on the application of analytical mechanics mechanism, the theory of mechanic vibrations, the theory of electric fields, fundamentals of geophysical measurements and computational mathematics are used in the given work. Scientific novelty – the methods of vertical vibrations impact estimation of traction vehicles on the soil density change got a further development; a new method allowing to determine the dynamic impact of traction vehicles running systems on the soil without its structure destruction directly under operation conditions was developed. Practical value: the obtained results of the given work are used by the association – producer of tractors, engines and spare parts “UkrTractor”, by Kharkov Tractor Plant (KhTP) for implementation at development of perspective and modernization of new models of traction vehicles of home manufacture, by the National Scientific Centre “Institute of Soil Science and Agrochemistry after A. Sokolovskiy” at carrying out scientific investigations. Field of application: at enterprises that deal with the production and updating of tractor models in use and tractors certification.
