Friction coefficient between glass surfaces and soft materials

The dry sliding friction between glass surface and soft materials like paper, towel and cloth for wiping glasses was explored experimentally. The UMT- 2 Tribometer has been fitted with a unidirectional oscillator including a mass-spring system. With a linear speed ranging from 0.05 to 8mm/s, a mass...

Description
Summary:The dry sliding friction between glass surface and soft materials like paper, towel and cloth for wiping glasses was explored experimentally. The UMT- 2 Tribometer has been fitted with a unidirectional oscillator including a mass-spring system. With a linear speed ranging from 0.05 to 8mm/s, a mass weighing 242 grams was sliding across planar surfaces covered with soft materials. The values of static and dynamic friction coefficients have significant variation as a function of linear speed and soft materials. The transition between the stick-slip process and continuum sliding has also been demonstrated experimentally. A theoretical model for variation of the dynamic friction coefficient as function of linear speed has been included in the dynamic equations of mass displacement. The dynamic equations have been solved by Runge Kuta method and compared with experimental results.
