Heat Generation and Friction in Rotating Bands

Abstract

In a numerical model of sliding friction, it is found that surface melting of the rotating band usually occurs before the system has travelled one bund length. Once melting had initiated, it was found that limiting the surface temperature to the melting temperature allowed the coefficient of friction to be found as a dependent parameter. The resulting coefficients of friction agree reasonably well with those found experimentally for rotating bands, particularly if residual heat in the tube is allowed for. The discrepancy between field tests and laboratory tests with pin-disk machines is explained on a basis of insufficent size or pressure to achieve local melting.
