Abstract

This study investigates the frictional and surface strain behaviour of silicone hemispherical finger pad simulants with different stiffness during tribological interactions with a smooth glass plate. A novel contact area and strain measurement method employing a digital image correlation technique was employed to give new understanding of the pad behaviour during sliding. The frictional behaviour of the sliding finger pad simulant is dominated by the adhesion mechanism, with a small overall contribution from deformation, as suggested by the high principal strains at the edge of the contact area. The strain behaviour is also influenced by the magnitude of the normal force and the stiffness of the samples.

刚度对滑动指垫模拟物的摩擦力、表面应变和接触面积的影响
本研究探讨了不同硬度的硅胶半球形指垫模拟物在与光滑玻璃板进行摩擦学相互作用时的摩擦和表面应变行为。采用数字图像相关技术的新型接触面积和应变测量方法,对指垫在滑动过程中的行为有了新的认识。滑动指垫模拟物的摩擦行为由粘附机制主导,总体变形贡献较小,接触区域边缘的高主应变表明了这一点。应变行为还受到法向力大小和样品硬度的影响。
