TLDR
In this paper, a method for calculating the pressure distribution, film profile, leakage rate and friction of a rectangular section rubber seal as used in hydraulic rams and jacks is described.Abstract:
This paper describes a method for calculating the pressure distribution, film profile, leakage rate and friction of a rectangular section rubber seal as used in hydraulic rams and jacks. The two basic equations, those describing the hydrodynamic pressure generation and the deflections of the seal surface have been solved simultaneously by numerical techniques. A solution was obtained which predicted film profiles qualitatively similar to those obtained experimentally. Solutions for outstrokes were obtained over ranges of variables as follows: sealed pressure (lbf/in2)…200–1,500500500sliding speed (ft/min)….150.5–25.015rubber hardness (IRHD).858555–85 Presented at the 29th Annual Meeting in Cleveland, Ohio, April 28–May 2, 1974read more
