Pressurized Oil Squeeze Film Dampers

Journal of Lubrication Technology, 1980
A pressurized oil squeeze film damper supporting a rigid rotor mounted in antifriction bearings is investigated. Orifice and inherent feed inlets are examined, and it is shown that the clearance determines the inlet resistance for a groove or slot. The film stiffness and damping forces are determined as a function of the restrictor coefficient, rotor ...

Disjoining Pressure and Film Tension in Comb−Graft Copolymer-Stabilized Oil Films

Langmuir, 1999
Thin, supported decane films stabilized with comb−graft copolymers were studied as models of polymeric surfactant stabilized water-in-oil emulsions.

Measurement of Oil-Film Pressure in Engine Bearings Using a Thin-Film Sensor

Tribology Transactions, 2002
Editor's Note: Anyone who thinks that STLE isn't on the cutting edge of MEMS technology should read this paper. In it, the authors have measured oil pressures which occur in main and connecting rod bearings using vacuum deposited thin film pressure sensors measuring less than a millimeter wide and just a few microns thick. Their careful work shows that

Embedded Optical Sensor for Oil Film Pressure Measurements in Journal Bearings

Smart Materials, Adaptive Structures and Intelligent Systems, Volume 1, 2008
The oil film pressure is one of the essential functional parameters in journal bearings. Until now, the oil film pressure has been estimated by theoretical calculations, since the measurement of oil film pressure has been a demanding or even unfeasible task in journal bearings, especially in bearings carrying dynamic loads. In this study a new approach

Pressure Distribution in Squeeze Film Dampers with Oil Hole Feed

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 1994
To improve the damping capability of squeeze film dampers, oil hole feed rather than circumferential groove feed is a practical proposition. However, circular orbit response can no longer be assumed, significantly complicating the design analysis. This paper details a feasible transient solution procedure for such dampers, with particular emphasis on ...

Tapered Spool Controller for Pressurized Oil Film Bearings

Proceedings of the Institution of Mechanical Engineers, 1969
The first part of this paper is concerned with the description of the different methods commonly used in compensating pressurized oil film bearings. The load-oil film thickness relationship for different methods of compensation and the power dissipated in bearings are given for the sake of comparison.

Transducers for pressure, temperature and oil film thickness measurement in bearings

Sensors and Actuators, 1982
Abstract Thin-film manganin pressure transducers have been developed for in situ pressure measurement in lubricated contacts. They are sufficiently small to allow resolution of the pressure spike, predicted by EHL theory. In addition, a resistance transducer for the simultaneous measurement of temperature and a capacitive transducer for the ...

Oil Film Thickness and Pressure Distribution in Elastohydrodynamic Point Contacts

Journal of Mechanical Engineering Science, 1982
In this paper, a general numerical solution to the elastohydrodynamic point contact problem is presented for moderate loads and material parameters. Isobars, contours and regression formulae describe how pressure and oil film thickness vary with geometry, material properties, load, and squeeze velocity, when the rolling velocity vector is at various ...
