Vliv okrajových podmínek zatížení na dynamický oděr pryže

This thesis deals with the problematics of dynamic wear of cured rubber compounds under dynamic loadings, to witch tire treads may be exposed during their performance in off-road conditions. In the first chapter of the theoretical part the basic factors that affect the wear of tread were described. The second chapter describes summary of current methods of cured rubber compounds testing and mechanism of tread wear in off-road conditions which is called cut and chip (CC). For the experimental part, two cured rubber compounds based on uncured rubber compounds with a variation of the rubber were chosen. These cured rubber compounds were tested for fundamental mechanical properties. The primary part of the experimental chapter is then focused on the influence of variations of boundary conditions of dynamic loadings and their resulting dynamic wear. For these analyses was used method to characterize the wear resistance under dynamic loadings. The results showed significantly different behaviour of used cured rubber compounds in context with variations of rubber and the contribution of the chosen method to simulate real tread wear in laboratory conditions.
