Abstract

Work in progress at the Institut National de Recherche et de Securite (INRS) is the study of the mapping of the slip resistance of industrial surfaces. INRS has acquired a portable device, which permits the measurement of a dynamic friction coefficient between a braked wheel and the floor surface to be assessed. This second part of the article thus begins with the identification of the experimental conditions under which the results obtained using the portable device is strongly correlated with the measurements taken using the non-portable apparatus developed at INRS. The experimental parameters studied here are the travelling speed of the portable device and the sliding ratio of the braked wheel. The sliding and the rolling speed of the braked wheel depends on these two parameters. Then, we examine the stability of the measurement of the dynamic friction coefficient, in order to ensure that a small margin of error in the experimental conditions does not have a significant effect on the measurement of the dynamic friction coefficient. We explain the influence of variations of the sliding and rolling speed of the braked wheel, on the dynamic friction coefficient, by modelling the lubricant squeeze film process.
