Thermoelastic Phenomena in Lubricated Sliding Contact.
Abstract
Lubricated sliding motion is studied for thermoelastic effects, notably an instability that causes large thermoelastic deformation of a nominally flat surface. A configuration similar to a face seal is used, with one face consisting of a thermal conductor and the other of an insulator. The roles of the pertinent parameters and material properties are delineated. Simple equation is given for the threshold of thermoelastic instability when both faces are initially flat. For the case of an initially wavy conducting face, the model for viscous heating envisages a full, coherent film on the one hand and, on the other, a broken film with zero heating in the cavitation zones. For both models, the continuous thermoelastic deformation of the conducting face, with changing sliding speed, is discussed and criteria for the onset of instability are presented. Experiments are reported to corroborate the findings of the theoretical analyses. (Author)
