Research on the Characteristics for Unsteady Mixed Lubrication in Metal Rolling Processes
|
Abstract:
According to Tsao and Sargent's hypothesis,the basic model of unsteady lubrication in mixed film lubrication regime in strip rolling was presented.A systematic analysis of the corresponding distribution of friction stress and pressure stress at various surface roughness and time during the impact of sinusoidal back tension stress was made.At a certain reduction the influence of the surface roughness at different time on the distribution of friction stress and pressure stress was also analyzed.Results indica...
