摘要

The thermal and thermo-mechanical phenomena between the sliding components are associated with frictional heating. Such frictional heat results from the relative dry sliding motion between contacting solids. The present article is to determine transient temperature distributions of multilayed bodies subject to frictional heating, without and with elastic deformation. The sliding system may consist of one or more than one two layer composite cylinders and a thin plate. The theoretical formulation is divided into two categories: friction in company without elastic deformation of the sliding bodies and friction with the elastic deformation. Compared with the first case, the second is more complicated since deformation energy is dissipated into heat stored in the deformation parts and affects the temperature distributions in the bodies. At first, a set of governing equations is developed for zero elastic deformation. Consequently, these equations are modified to taking the elastic deformation into account, by introducing the dissipated deformation energy as the source term. The Hert's theory of the contact is applied to derive the deformation energy.
The numerical approach is developed to determined the temperature distributions in the sliding bodies and no artificial division of frictional heat between the two surfaces in the sliding system is needed. The effects of the elastic deformation on the temperature distributions are discussed in detail. The analysis shows that the effect of the deformation energy may be severe for the deformable materials (for example, rubber).
