Abstract

Scuffing, a major cause of failure in automobile engines, is considered asa dynamic process in this study. Local adhesions may occur randomly in lubricated contacts due to the existence of asperity contact and breakdown of lubricating films. Scuffing would take place if the local events develop rapidly into a large-scale plastic deformation and catastrophic failure. A system dynamic established in the present paper allows one to predict dynamicbehavior of a tribological system through numerical solutions of a group of differential equations. A simplified analysis based on this model confirms that the system will develop into a state of instability if the friction force at the interface increases with temperature.
