Title：Issues and Challenges in Friction of Mechanical Components

Abstract：Friction that occurs when two components slide or roll against each other is primarily responsible for energy efficiency of the mechanical system. Hence, in order to conserve energy and prolong the life of machines, optimization of frictional interaction is critical. Despite extensive research over the past decades, control of friction in many mechanical systems is not readily achieved. In this presentation, the issues and challenges associated with friction phenomena will be discussed. Current understanding of the mechanisms of friction and its behavior in dry and lubricated contacts will be presented. Also, methods to reduce wear of mechanical components based on surface stiffness control will be introduced. This presentation will be sufficiently general for a wide audience with various technical backgrounds.
