Theoretical Evaluation and Experimental Measuring of the Friction Forces from the Sealing of the Rod for the Hydraulic Cylinders

Abstract

The paper presents some technical problems specific to the mobile sealing, used in the construction of hydraulic cylinders, and the theoretical and experimental methods which allow to determine the friction forces which appear in the sealing of the rods. There are presented, under the graphical shape, some theoretical results obtained by the method of the mathematical modelling and numerical simulating and, also, some experimental results obtained with an experimental device mounted on a test bench used for the friction forces experimental measuring.
