RESEARCH OF THE DYNAMIC PRESSURE VARIATION IN HYDRAULIC SYSTEM WITH TWO PARALLEL CONNECTED DIGITAL CONTROL VALVES

ABSTRACT The researches of the hydraulic system which consist of two straight pipelines sourced by two separate 3/2 hydraulic fast switched valves. A constant throttle is switched between each of them. The results show pressure dynamic variation in the pipelines in the form of transient characteristics due to the synthesis of a simulation model. The researches aim to analyze the influence of the section size of the fixed throttle, as well as the phase delay in the control signal to the valves, over the pressure characteristics in both parallel pipelines. The results of the present research can be used as a fundament for the construction of digital hydraulic control systems.
