The Analysis of the Dynamic Response of the Hydrostatic Driving Systems in a Closed Circuit
MetadataShow full item record
The hydrostatic actions in a closed circuit were remarked in the action of the technological equipment both for achievement of translation motions with linear hydrostatic engines with bilateral stem and for rotational motions with rotative hydrostatic engines. The advantages of a closed circuit result from the compactness of the whole installation, the efficient control of the mouvements at the starting and braking of the working element, the efficient control of the movement velocities of the working element and directly, through the adjustment of the cylinder volume and the smaller power consumptions then the open circuit. This paper present the results of a dynamic analysis for closed circuit hydraulic driving systems. The analysis was maded for two types of actions: with rotative, respectively, with linear hydraulic motor. The authors present the diagrams obtained for a few operating regimes.
