Taissir M. Increase of efficiency of autonomous steering hydrounit by the rational choice of his parameters

Object of research - hydrodynamical transients in the independent steering hydrounit. The purpose of research - research of the independent steering hydrounit of the raisedprofitability and reliability with the minimal dimensions. Methods of research - system analysis, methods of the theory of hydrounits, methods of the theory of mechanisms and machines, optimum control, theory of mathematical modeling of hydromechanical systems. Practical value - mathematical model of the steering hydrounit; techniques of research of dynamic processes in system "a steering surface - hydrounit"; the recommendations for increase of efficiency of their work at use of pumps with volumetric management. Area of application - machine with use of the independent steering hydrounit. Scientific novelty - the regime characteristics of the volumetric hydrounit are established, at which its dynamic rigidity is higher, than hydrounit; the new law of course of working process in the hydrocylinder is opened; the analytical expressionfor definition of the moment on an inclined washer of the pump is received at small corners of a deviation and at absence of loading on the pump; the influence of feedbacks on a rule and till angular speed of a rotor of the electromechanical converter on dynamics of the steering hydrounit is established; mathematical model of system of the independent steering hydrounit at the expense of the simultaneous account of dry friction.
