到不平的表面的启发简历的 microfibre 数组的粘附理论上被学习。数组由在僵硬退出层，和表面上修理的垂直的有弹性的杆组成被僵硬的步与通常分布式的高度建模。分析表达式在途径和收回进程为粘附力量被获得。它被看那，与增加预装，脱力量起初增加然后达到高原价值。结果同意以前的实验并且被期望在在实际应用程序的数组的粘附控制有用。

英文摘要：

Adhesion of bio-inspired microfibre arrays to a rough surface is studied theoretically. The array consists of vertical elastic rods fixed on a rigid backing layer, and the surface is modeled by rigid steps with a normally distributed height. Analytical expressions are obtained for the adhesion forces in both the approach and retraction processes. It is shown that, with the increasing preload, the pull-off force increases at first and then attains a plateau value. The results agree with the previous experiments and are expected helpful in adhesion control of the array in practical applications.
