Processes of the abrasive wear-out elastomers and their connection with viscoelasticity qualities

摘要

The blow stress as the oscillation damping process has been examined here and the equation for the calculation of the viscosity quantities characteristics of the elastomers have been obtained. The viscosity quantities characteristics depended on the test temperature have been determined. In result of elastomers wear on different plants the following principal regularities of thermal kinetics of their abrasive wear-out have been determined: the wear-out minimums that are out-side of zones of resonance absorption energy by rubber structures have been determined; the wear-out intensity depends on the principle of the temperature-time and the temperature-structure superposition; the activation energy of the destruction processes under the abrasive wear-out is equivalent to α-process energy of the mechanical glassing. The destruction mechanism of elastomer surface depended on their relaxation quantities have been determined; in a field of the high-elastic deformation there is a dependence close to a linar between logarithms of the intensity wear-out and the absorbed energy density. The application of elastomers in tribological system have been offered.
