Abstract
Fretting wear has a significant influence on wire rope fatigue life when in cyclic bending, particularly for crossed-wire
contacts, where the interfacial motion of the surfaces is complex and multi-axial. To simulate these contacts in a
controlled manner, a laboratory-scale, crossed-cylinder, reciprocating fretting wear test was developed. A broad range of
contemporary lubrication technologies were evaluated using this method and a systematic multivariate statistical analysis
was performed to identify the most significant lubrication-related parameters with respect to these fretting wear
conditions. Wear area increase per slip cycle was the most relevant measure of wear damage, as this captured the
influence of changes in the fretting wear regime during the test. The ability of a lubricant to reduce damaging fretting
wear during the run-in phase was the biggest influence on long-term fretting wear, particularly for grease-lubricated
contacts.
