SURFACE TEMPERATURE IN OSCILLATING SLIDING INTERFACES

摘要

A model is developed to predict the behavior of two sliding bodies undergoing oscillatory motion. A set of four dimensionless groups is introduced to characterize the transient dimensionless surface temperature rise. They are: the Peclet number P{sub}e, the Biot number B{sub}i, the amplitude of oscillation A, and the Hertzian semi-contact width. Also considered in the analysis is the effect of the ratio β= A/α of the amplitude to the semi-contact width. The results of a series of simulations, covering a range of these independent parameters, are presented and examples are provided to illuminate the utility of the model.
