Molecular dynamics study on friction of polymer material polyamide 6 (PA 6)
ABSTRACTThe resin material PA6 has a wide range of application in engineering due to its excellent mechanical properties. The friction behaviour of PA 6 was studied using molecular dynamics simulation method in this study. The effects of temperature, sliding speed and wear depth on the friction performance of PA6 were studied, and the surface micromorphology of PA 6 model also was analysed. The main conclusions are as follows: Within the temperature range selected in this experiment, the temperature has no significant influence on friction and surface micromorphology of PA6. As the friction speed decreases, the friction decreases slightly. The coefficient of friction increases slightly with the increase of friction speed. The greater the wear depth is, the more pronounced the ploughing and debris accumulation on the surface of PA6 is. The friction coefficient increases slightly with the increase of wear depth, but not significantly. The greater the wear depth is, the larger the friction fluctuation is.KEYWORDS: Molecular dynamics simulationPA6frictionslidingtemperature Disclosure statementNo potential conflict of interest was reported by the author(s).
期刊介绍:
Molecular Simulation covers all aspects of research related to, or of importance to, molecular modelling and simulation.
Molecular Simulation brings together the most significant papers concerned with applications of simulation methods, and original contributions to the development of simulation methodology from biology, biochemistry, chemistry, engineering, materials science, medicine and physics.
The aim is to provide a forum in which cross fertilization between application areas, methodologies, disciplines, as well as academic and industrial researchers can take place and new developments can be encouraged.
Molecular Simulation is of interest to all researchers using or developing simulation methods based on statistical mechanics/quantum mechanics. This includes molecular dynamics (MD, AIMD), Monte Carlo, ab initio methods related to simulation, multiscale and coarse graining methods.
