A discussion of the tribological phenomena under minimal load using molecular dynamics

Abstract

This study explored the tribological phenomena under minimal load using molecular dynamics. In the simulation, ensemble average standards and the Condensed-phase Optimized Molecular Potential for Atomistic Simulation Studies potential energy function were used. Regarding materials, this study used (5, 5) carbon nanotubes (CNTs) to move the copper atoms in order to obtain the coefficient of friction (COE) between the single-wall CNTs and copper atoms before analyzing the tribological phenomena under minimal load and changes in friction. This study found that, under an extremely tiny load, the direction of the resistance of the relative sliding is not always in the opposite direction of the movement direction. The influence of environment temperatures on the COE was that the environment temperature increases, the number of fluctuation also increases, but the COE reduces. © 2013 The Author(s).
