Study of instantaneous starvation at a finite-length line contact

Abstract

Starvation phenomenon widely exists in the non-conforming contacts when high-viscosity lubricating oil or greases are used. However, most of the work focuses on the steady state starvation, and the phenomenon of instantaneous starvation is not well explored by scholars. This paper experimentally studies the effect of speed, base oil viscosity and load on instantaneous starvation, and proposes some improvement measures to weaken the instantaneous starvation.
