...22, also from Hess and Soom (1990). The data presented were acquired driving their pin-on-disk contact at three different frequencies. Figure 22(b) shows the friction curves predicted by their model with frictional memory modeled as a pure lag and should be compared with the experimental data illustrated in Fig. 22(a). Indicative of the progress of triboiogy, the friction model of Hess and Soom (1990) which accounts for contact geometry and loading, material properties, velocity, lubricant viscosity and Stribeck friction, is to a large degree based on contact and lubricant parameters, only three parameters are fit a p o s t e r i o r i to the data....

...The data of Bell and Burdekin (1966, 1969) and Hess and Soom (1990) indicate such a curve. When boundary lubrication is more effective, the friction is relatively constant up to the velocity at which partial fluid lubrication begins to play a role. Vinogradov et al. (1967) and Khitrik and Shmakov (1987) present data supporting a flat (f-v) curve through the region of boundary lubrication, as suggested by curve (b) of Fig....

Evidence for frictional memory is available from a range of experimental sources: Sampson et al. (1943), Rabinowicz (1958, 1965), Bell and Burdekin (1966, 1969), Walrath (1984), Rice and Ruina (1983), Hess and Soom (1990). Tribology is not yet able to offer a theoretically motivated model of the frictional memory, though Xiaolan and Haiqing (1987) numerically investigate transient elasto-hydrodynamic lubrication using an analysis that starts with Reynold's equation and Hertzian contact analysis; with this they find a time lag of 3 ms between velocity and friction changes in simulated sliding contact....
