The purpose of work - development of theoretical bases of account of parameters, which define quality of work of hydrosystem, on the basis of which there can be created effective techniques of a choice of structure and parameters of complex dynamic system of a hydrodrive of the mobile machine with numerous executive engines. Methods of researches - mathematical modeling of hydrodrives of mobile machines; numerical experiment on research of models of hydrosystem of mobile machines. The analysis of a condition and перспективности of development in a direction of minimization of quantity of pump elements of the mobile machine is carried out; the presence of significant quantity of development in different areas of an industry - metallurgy, manufacture of agricultural machines, road and other mobile machines is shown which confirms a urgency of the given direction of researches. The mathematical models of a hydraulic drive of the self-propelled machine with numerous hydroengines are developed. The algorithm of research of stability and quality of work of the given hydrosystems is fulfilled by computing experiment with the help PIBM. The qualitative dependences of influence of parameters of system on its characteristics are shown. The experimental researches of physical model of a group hydrodrive with two consistently connected hydromotors are executed. The comparisons of results of experimental and numerical experiments are given, the reliability of the accepted mathematical models is shown. The ways of increase of stability and quality of work of a group hydrodrive are offered. The methodical bases of account of hydrosystems with several hydroengines are developed. The technique of definition of parameters of such systems and choice of their structure is offered. The created program of the automated account GGP with 2 hydromotors.
