Jan 01, 1990 · Although many contacts operate under unsteady loading and sliding conditions, friction behavior under such conditions is still not well understood. In this paper we report on a series of experiments that were run to examine friction-velocity characteristics of line contacts operating under unsteady sliding velocities in the mixed, elastohydrodynamic and hydrodynamic lubrication regimes. A
Jul 28, 2021 · The sliding contact line installed on the bottom or both sides of flat car will affect the passing of other vehicles, but it is an important choice for pipeline production and transportation equipment because of its low Mesa.
