Abstract: An
accurate calculation of stress field based on elastic-plastic
finite element method by means of Siemens computer showed that
both hardness difference and coefficient of friction are
important factors to affect on fatigue failure of
rolling-sliding contact. An experiment on fatigue life of
rolling-sliding contact was carried out in condition of various
hardness difference by a two-roller-type rolling contact fatigue
tester.
