Panchenko A. The development of the scientific base of planetary hydraulic motors design with required output features

Hydraulic, hydrodinamic and mechanical processes of the interaction of working liquid flow with planetary hydraulic motor elements in composition of mobile machine hydraulic unit; the interaction processes which influence on the value of its output features. The improvement of the planetary hydraulic motors output features in composition of mobile machines hydraulic units by studying of displacing and distributing blocks working processes on the base of the of more complete hydraulic motor and its units mathematical models development. The development allows to improve the design base of the unified rows family of planetary hydraulic motors with given output features. The mechanical methods of liquid and gas, which helps to define the pres-sures of the working liquid in clearance; the system analy-sis, which has allowed to research the processes, occurring in the hydraulic motors systems in case of their irrational design; the methods of mechanisms and machines theory which have allowed to describe the change of the output features of the planetary hydraulic motor during the mainte-nance; the methods of simulating modeling, which have allowed to research the regularities of the change of the planetary hydraulic motor output features in maintenance conditions. The complex of structural and schemes for the calculation of the static and dynamic fea-tures planetary hydraulic motor in composition of hydraulic unit is designed; methods of step-by-step decision of put scientific problem from the choice of the definite object, development of mathematical model and software for pa-rametric studies and planetary hydraulic motor dynamics studies till practical recommendations formulation are also designed. The working processes of displacing and distrib-uting blocks, the planetary hydraulic motor output features on the base of their more complete mathematical models development for improvement of the planetary hydraulic machines designing base are researched. The practical rec-ommendations for designing of unifiedrows family of the high-moment hydraulic motors are developed. The results of the work are stated as recommendations for designing. The developed design documentation is sent to Open Joint-Stoks Society "Yampolskiy instrument-making factory", Open Joint-Stoks Society "KB Berdyanskselmash", Joint-Stoks Society "Hydroinpex".
