摘要
建立了三层模型,定义了上层滑动表面与中间润滑层的最大静摩擦力和最大动摩擦力.通过数值模拟研究了润滑层对相对运动的固体表面最大静摩擦力与最大动摩擦力的影响.数值模拟结果给出了最大静摩擦力和最大动摩擦力与上层固体和中间润滑层原子间的倔强系数的关系.
T hree‐layers model has been built , and the maximum static friction and maximum dynamic friction force of the upper and the middle lubricant chain are defined . The effects of the lubricant chain on the maximum static friction force and maximum dynamic friction force of solid surfaces with relative motion are studied through numerical simulation . The results show that the friction force is related to the stiffness strength .
