Abstract (en)
This dissertation investigates the influence of rubber hysteresis, used
for manufacturing shoe soles, on the coefficient of friction in contact
between footwear and floor. In addition to experimental testing,
numerical methods (regression and the Taguchi method) were
employed to analyze the results and define the influence of certain
parameters on the coefficient of friction. An artificial neural network
was also developed to predict the coefficient of friction between
footwear and the floor based on the hysteresis values of rubber and
other influencing parameters.
For the purpose of experimental determination of the coefficient of
friction, a special testing table was designed, capable of testing under
various conditions and with parameter variations (sliding speed,
normal load, different types of surfaces, surface conditions, roughness).
Experimental investigations included determining the hysteresis of the
rubber compounds used in the tests, measuring the hardness of the
rubber, and assessing the roughness of granite plates on which the
rubber samples were slid.
The experiments indicate that the influence of rubber hardness on the
coefficient of friction cannot be considered separately from hysteresis.
Larger variations in the coefficient of friction (up to 18 times) on
smooth plates suggest that hysteresis has a smaller influence due to the
dominant role of adhesion in determining the coefficient of friction. On
anti-slip plates, which are significantly rougher than smooth plates,
variations are smaller (up to 3 times) because hysteresis has a greater
impact on the coefficient of friction due to the deformations caused by
the movement of the rubber over the rough surface.

“Data exchange” service offers individual users metadata transfer in several different formats. Citation formats are offered for transfers in texts as for the transfer into internet pages. Citation formats include permanent links that guarantee access to cited sources. For use are commonly structured metadata schemes : Dublin Core xml and ETUB-MS xml, local adaptation of international ETD-MS scheme intended for use in academic documents.
