Resumen en inglés
Despite the hydraulic systems are among the oldest means of energy transmission used by man, currently they are receiving special attention in scientific researchs. The search for greater control of energy generated spurred an increase in the use and application of technology and new research such systems. Besides high capacity of control and precision, sensitivity, stiffness, speed, strength, power hydraulic systems give a complete set of properties allowing their wide applications in many different areas. But the non-linearity of the dynamics of its parts is the modeling of hydraulic system is complex. Knowing that pumb is the most important part of the hydraulic circuits, this study presents a mathematical model and computer stimulation of a vane-type pump offset by pressure with integral control type. The theoretical model is based on the application laws of physics in four parts of the pumb: Newton's law of the spool valves and the coupling of the piston ring and with the Law of Conservation of Mass in volumes of controlling the pressure, and the Po inside if the carcass (pressure in the slave cylinder), Pcc. The behavior of the system was checked with the application of a hydraulic load (request) type entry step. Thus the pressure, leaving the system, presents a transient at the beginning of the simulation and quickly enter into arrangements. At the moment in which the hydraulic load transient operates the back and then enter into arrangements with the same value as presented before the step, specific behavior of systems with full control type.
