Abstract

Abstract: Methodology to estimate temporal and spatial variation of friction coefficient in partial slip contacts using reciprocating full-sliding tests is presented. Basic assumption is that surface modification and consequently the friction variation is a function of sliding distance. Friction coefficient is obtained as a function of sliding distance from the reciprocating full-sliding tests with low amplitude sliding at the contact interface. An analysis tool is used to estimate the slip in the interface for a given cycle. Cumulative slip at each point in the interface is used to predict the friction coefficient using friction curves generated from the full-sliding tests. Average value of the estimated friction coefficient variation was found to be in reasonable agreement with the values measured experimentally. Abstract : Highlights: Friction coefficient vs. sliding distance got from reciprocating full-sliding tests. Analysis was used to estimate cumulative slip at each point in contact interface. Friction coefficient variation was estimated from cumulative slip using friction curves Estimated average friction coefficient matched well with experimental values.
