THE ISSUE OF THE INFLUENCE OF WEAR ON THE TEMPERATURE FIELD OF A FRICTION COUPLE

Journal Title: Tribologia - Year 2012, Vol 241, Issue 1

Abstract

Trials for the identification of the temperature field of friction couple elements have been made in numerous experimental and theoretical researches. The direct investigation of temperature taking into consideration the actual thermal condition give only partial information about that temperature field. On the other hand, well-known models of the frictional warming of solids are based on the equality assumption of friction work and heat. This means that, during consideration, the models' authors have ignored the energy dissipation that was caused by wear. This article presents the model generalisations of thermal processes caused by friction, which take into consideration the losses of energy due to wear. To obtain a clear and unambiguous interpretation of the results, a pair of friction elements that have linear temperature distribution was presented in the form of thin-walled pipes of face contact. The temperature of friction contact and the distribution of temperature in individual pipes are described. The authors took into account the following: physical properties of materials, conditions of heat exchange with the environment, the time of friction, wear, and some geometrical characteristics of rubbing parts. In order to illustrate the impact of wear on the temperature field, the model of rubbing thin-walled tubes, based on the assumption of the equality between work and the heat of friction was used. Then the presented models are compared. Computational examples are developed with the use of Delphi and Excel programs. The significant influence of wear on the course of thermal processes is presented. This is reflected as a reduction in frictional contact temperature, whose value can not exceed the flash temperature. The examples illustrate the impact of cooling and the physical properties of the frictional materials on the temperature field of the friction pair.
