Molecular Dynamics Simulation of Friction for MEMS Application
Proceedings of the ASME International Mechanical Engineering Congress (2003, Washington, DC)
Abstract
Adhesion and dry sliding friction are modeled and simulated using molecular dynamics principles in this study. The interaction between two aluminum surfaces is simulated since the focus of this study is on the atomic-scale frictional characterization of metallic microcomponents. The Morse potential function is used to calculate the intra- and inter-atomic forces between the atoms of the sliding surfaces. Results are presented that simulate the adhesion process when the surfaces come in contact. Also, the calculated coefficient of friction for various values of contact pressure, sliding speed and asperity level are presented. The general trends observed here agree with the results obtained by other researchers for different materials.
