Abstract
We study the influence of surface roughness on the adhesion between elastic solids. We present experimental data for the force necessary to pull off rubber balls from hard rough substrates. We show that the effective adhesion (or the pull-off force) can be calculated accurately from the surface roughness power spectra obtained from the measured surface height profile.
摘要
我们研究了表面粗糙度对弹性固体间粘附力的影响。我们给出了将橡胶球从坚硬粗糙基底上拉开所需力的实验数据。我们表明，有效粘附力（或拉开力）可以根据从测量得到的表面高度轮廓获取的表面粗糙度功率谱精确计算得出。
