Dynamic wear evolution of steel wires during multi-axial fretting-fatigue

Abstract

In order to study the dynamic wear evolution of steel wires during multi-axial fretting-fatigue, experiments were carried out on a self-made multi-axial fretting fatigue test rig. The results show that the maximum length, maximum width, area and depth of wear scar will increase with the fatigue cycles, and the cross angle decreases from 11° to 4° with increasing fatigue cycles. The wear coefficient increases quickly at first and then tends to be stabilized when fatigue cycles increases from 5000 to 20000.
