Shevchenko I. Improving the efficiency of transmission of active working parts of agricultural machinery

Thesis deals with the objectives of improving operational and technological indices of agricultural machines with active workers' bodies in their aggregation with tractors of class 30 kN. The object of study - the process of active functioning of the drive working bodies of agricultural machinery. Objective - improve the efficiency of the drive active working parts of agricultural machinery by reducing the dynamic loads. We used the analytical and experimental research methods, based on the use of the core assumptions of the theory of dynamical systems, mathematical modeling and application of modern measuring systems controlled settings. Experiments were carried out on the stands and agricultural units in the performance of different processes. The main scientific result of the thesis - a theoretical basis for reducing the dynamic loads drive active working bodies of agricultural machinery. First: offered the variation of dynamic loads drive the active working parts of agricultural machinery for assessing and justifying the most dangerous of their importance is demonstrated approval of the minimum expenditure of energy during acceleration active working parts of agricultural machinery. Improved dynamic model of the agricultural unit to drive the active working bodies of farm machinery from the PTO of tractor different from the known fact that can take into account modes of dispersing it in the performance of various technological processes. Were further developed: the theory of the agricultural unit with active working bodies, developed in the direction of evaluation of the resonant phenomena of the drive; methodology to assess performance drives active working bodies of agricultural machinery. The practical significance of the results: mathematical models of agricultural units with active workers' bodies, embodied in the Enterprise "Institute of machines and systems," Industrial Policy and the National Academy of Sciences of Ukraine, established the rational parameters of the PTO tractor Series KhTZ-150K, KhTZ-160 and KhTZ-170, which adopted to the implementation at JSC "Kharkiv Tractor Plant"; practical recommendations to ensure effective operation of the drive active and working bodies of silage corn harvesters were introduced in the agricultural enterprises of Kharkov region.
