Abstract:

The characterization of the behavior of a lubricant in an elastohydrodynamic contact is shown to depend upon the nonlinear viscoelastic response of the fluid. This response can be obtained from the experimentally determined linear viscoelastic properties of the lubricant. An experimental program for the measurement of these properties is outlined and some illustrative results are given. Methods of treating the data and the implications of the data thus far obtained are briefly summarized. The directions in which continued investigation is likely to prove most successful are examined and a specific research program along these lines is sketched.
