Abstract

The work aims to investigate the formation and evolution mechanism of lubrication failure in mechanical transmission systems under extreme operating conditions, focusing on the effects of speed-induced variations on oil film interface slip and elastohydrodynamic lubrication (EHL) characteristics.

Key words
