采用粗粒化分子动力学模型研究磁头飞行高度、磁盘速度、头盘界面压强差和润滑剂厚度对Zdol润滑剂转移的影响。结果表明，随着磁头飞行高度的增加，润滑剂转移量呈先增加后急速增加的趋势；润滑剂转移量随磁盘速度的增加而增加，与低飞行高度相比，高飞行高度下磁盘速度对润滑剂转移量的影响更剧烈；润滑剂转移量随头盘界面压强差的增大而增大，与低飞行高度为相比，高飞行高度下头盘界面压强差对润滑剂转移量的影响最为明显；润滑剂转移量随润滑剂厚度增加而增加。

The effects of the flight height of the head, disk speed, pressure difference of the head/disk interface, and lubricant thickness on Zdol lubricant transfer were studied by using the coarse-grained molecular dynamics model. The results showed that with the increase of head flight height, lubricant transfer increased first and then increased rapidly. Lubricant transfer increased with an increase in disk speed. And compared with low flight height, the impact of disk speed on lubricant transfer at high flight height was more severe. Furthermore, lubricant transfer also increased with the increase of the pressure difference at the head/disk interface. And compared with the low flight height, the pressure difference had the most obvious effect on lubricant transfer at the high flight height. What’s more, lubricant transfer increased with the increase of lubricant thickness as well.
