Full textThesis for Scientific degree of candidate of technical sciences, specialty 05.22.02 – vehicles and tractors. National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2017. The work is devoted to solving the technical problem of development of calculation methods and choice of rational schemes of dual path hydraulic volume mechanical transmission (HVMT) wheeled tractors, which allows you to select the optimal scheme HVMT at the design stage. Actuality of work consists in the necessity of providing of competitiveness of Ukraine tractors. The analysis of work of the dual path HVMT tractors of foreign analogues is carried out. Refined mathematical model of hydrostatic axial-piston hydraulic machines as the main HVMT elements identity-based loss coefficients with the latest experimental data loss and coefficient of performance (COP). The algorithm and the computational procedure for the establishment of a oneto-one correspondence between the operating parameters and the efficiency of hydraulic drive system (HDS) losses in forward and reverse flow of power through the HDS for her work in the dual path tractor HVMT. Calculation-theoretical methodology and her programmatic realization is first worked out for determination of HDS parameters, dual path HVMT and basic technical and economic indexes of tractor-aggregate taking into account the modes of circulation of power, losses in HDS, HVMT and skidding of tractor for an analysis and prognostication of descriptions alternative tractor HVMT and scientific ground of the most rational transmission for a certain tractor. The problem of construction of universal descriptions of tractor is first set and decided with dual path HVMT. Original solution of task offers on visualization of kinematics, power and power parameters of dual path HVMT of the perspective Ukrainian tractors in all range of their operating modes as an important criterion for comparison of alternative schematics of HVMT. Universal descriptions of first in Ukraine and on post-soviet space of tractor of XTZ-21021 from stepless HVMT-1S development of NТU "KhPI" and propulsion MODULE of "XTZ" are built. Results numeral and natural experiments allow to draw conclusion, that the calculation-theoretical methodologies and constituents of them worked out in dissertation mathematical models are adequate and directed to on an increase efficiency and competitiveness of the Ukrainian tractors.

Full textThe dissertation for obtaining a scientific degree of Candidate of Science (Technology) on the specialty 05.22.02 – automobiles and tractors. – National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2017. The dissertation is devoted to increasing the braking efficiency of wheeled tractors with steady hydrostatic transmission due to the method of braking, the choice of shape and duration of the change of the parameter of regulation. The complex mathematical model of the braking process to tractor KhTZ -21021 with hydrostatic transmission is made possible to model all possible methods of braking. From the existing mathematical model, the kinematic, power and energy parameters of the steady continuously variable transmission are different, as well as the description of the drum braking mechanism with the pneumatic system in the wheel tractor KhTZ-21021. On the basis of the optimization theory it is formalized that the rational change of the hydraulic control parameter for the hydrostatic transmission with the "differential on the outlet", in terms of the braking efficiency, is a curved form. At the hydrostatic transmission laboratory stand, it has been confirmed that the best braking performance during braking with the hydrostatic transmission regulation parameter (the minimum number of revolutions of the output shaft hydrostatic transmission, and, as a consequence, the minimum braking distance) is observed for curved forms of hydrostatic transmission control, regardless of the duration of the control effect.
