Standardization of Friction Testing of Industrial Working Surfaces.

摘要

The design and construction of a portable friction measuring device for use on industrial working surfaces are described. Historical background obtained from the literature,reports of interviews with current friction testing device users,and study of the theoretical aspects of the measurement of the coefficient of friction of footwear on walkway surfaces provided the basis for the concept development for the device named the Universal Friction Testing Machine (UFTM). The operational characteristics of the presently available friction testing devices are described and compared with those of the UFTM. The results of a number of measurements made with the UFTM using rubber,leather,vinyl,and oak samples are reported. Conclusions are drawn from the tests with recommendations made to study further the frictional transition region between static and dynamic values of friction between footwear and walkway materials.
