ANALYSIS OF SPECIFIC PHENOMENA OCCURRING DURING THE OPERATION OF A CLOSED HYDRAULIC CYLINDER

In order to be able to analyze the specific phenomena occurring during the operation of a closed hydraulic cylinder, one should consider the loss due to the compressibility effect of the working fluid, as well as the volume loss in the piston-cylinder sealing area. The paper present a mathematical model that considers these compressibility and volume losses due to piston-cylinder sealing, upon actuating the piston according a specific law of motion. The solutions of the mathematical model and the analysis of the proposed solutions are presented.
