    Abstract:

    Fretting wear is a main failure form affecting key mechanical structures.In order to study the evolution of wear scar and stress field and their coupling mechanism,a cylinder/plane finite element contact model was established by ABAQUS software,and the evolution process of fretting wear scar and contact stress field was simulated based on Archard wear model.Further,the coupling mechanism of wear scar and stress field during fretting wear was analyzed.The simulation results show that the wear scar is "W"-shaped under partial slip,the contact width and wear depth increase slightly and the maximum contact stress and shear stress increase slightly with the increase of cycle times;under the gross slip,the wear scar is "U"-shaped,with the increase of cycle times,the wear scar becomes wider and deeper significantly,the stress field in the contact zone widens and flattens.
