- W2903156905 abstract "In this paper, a molecular dynamics model is proposed to describe the collision friction of a hinge mechanism in the space environment. The EAM potential is used to describe the interaction between atoms. Based on the model, the collision friction process and thermal properties between the indenter and smooth gold film surface at different indenter amplitudes, frequencies and crystal orientations are studied. The temperature distribution and collision friction mechanism of the gold film are analyzed. The simulation results show that increasing the vibration frequency of the indenter in a certain frequency range can reduce the friction force. The amplitude of the indenter and crystal orientations at different frequencies shows different effects on the average friction force and the surface temperature of the substrate. In addition, textures are also made on the gold film and the effects of texture width and texture depth on the friction and thermal properties are investigated. The results show that the textured surface can significantly reduce the friction force. The average friction force and the surface temperature of the substrate decrease with the increase of texture depth, and increase with the increase of texture width. The average friction force and the surface temperature of the substrate are more sensitive to the texture depth." @default.
