Polushkin K. Synthesis of systems of hydropneumatic units with parallel operating algorithms

Research object: working procedures in hydropneumatic units of automation objects. Research purpose: raising of technical level of hydropneumatic units by creation of methods of synthesis of systems with parallel operating algorithms, undivided decomposition of schemes, mathematical operating modeling of automation objects. Research methods: theory of fluid mechanics, thermodynamics, structure synthesis and analysis, method of complete minimization of standard position structure. Theoretical and practical results: the structure organization and on the basis of it circuit design style of hydropneumatic units with parallel operating algorithms with the use of complete minimization of standard position structure is developed that makes it possible to reduce the number of logical elements by approximately 41%. The mathematical operation real time model of positioning pneumatic unit used in the time of design of industrial robots is created. Scientific novelty: the algorithm of synthesis of systems of hydropneumatic units is developed that makes it possible to choose the rational scheme without the search of possible realization variants within the bounds of undivided decomposition of equations and to reduce engineering time by 50%. The mathematical operation model of positioning pneumatic unit of industrial robot is made that makes it possible to get the required law of motion of its output link by changing of effective areas of pilot pressure lines subject to real speed of pneumatic units. Degree of implementation: research results are used for development and modernization of hydropneumatic units in OP of Gidroeleks Corporation (Kharkiv) and in the educational process of the hydraulic machines department of NTU "KhPI".
