摘要
基于二维Frenkel-Kontorova模型,运用分子动力学模拟方法,研究了具有六角对称结构的系统从locked态到sliding态的相变,并数值分析了上层原子采用六角对称结构时,系统的不同参数对静摩擦力Fs和动摩擦力Fc的影响.
Locked-to-sliding phase transition is studied based on the two-dimensional Frenkel-Kontorova model in this paper. The method of molecular dynamics simulation is used. The effect of the static friction force on system parameter is investigated numerically when the upper layer atoms are of the hexagon symmetric structure.
