Aimed at exploring the continuous dry friction behavior at fretting interface, targeted at crystalline silicon-diamond coupled interface, the fretting interface model with single asperity for dry friction analysis is set up using LAMMPS (i.e., molecular dynamics simulation tool, MD). The micro-motion process is shown with clear images and symbolized with friction force response and the normal force. It is should be noted that during the whole process, including the intervals between direct friction contacts, there exists continuously turbulent force response. The results indicate that during the continuous single asperity contacts, influenced by the factors of stick-slip effects, deformation-recovery process and stress release of wore atoms, the friction contact intervals show friction response, possibly stronger than that of the direct friction contacts to the extent that the frictional characteristics of the coupled solid fretting interfaces can be affected.
