Fretting fatigue can easily causes surface wear and cross-sectional area loss of steel wire,which induces the steel wire fracture failure and thereby shorten the service life of steel wire rope.Different fretting fatigue parameters (contact load,fatigue load,wire diameter and crossover angle) cause distinct fretting fatigue wear characteristics of steel wire.Therefore,it is important to study the effects of fretting fatigue parameters on the fretting fatigue wear evolution characteristics of steel wires.The wire fretting fatigue wear model was constructed based on tribology theory and Marc simulation software.The effects of contact load,fatigue load,crossing angle and wire diameter on fretting fatigue wear evolution of steel wires were investigated.The results show that the fretting fatigue wear volume of steel wire is mainly related to the contact load and fatigue load.The wear depth,wear rate and wear volume of fatigue wire increase with the increasing of contact load.The wear volume of fatigue wires under different contact loads increases linearly with the increasing of fretting cycles.As the fatigue load amplitude increases,the wear depth,wear rate and wear volume of fatigue wire all tend to increase.The wear volume of fatigue wire increases linearly with the increasing of fretting cycles in cases of different fatigue load ranges.When the contact load,fatigue load and friction coefficient between steel wires are the same,the wear volume of fatigue wires for different crossing angles and loading wire diameters is the same.
