The phenomenon that the hard abrasive grains repeatedly cut the surface\nmaterial of the parts during wear is very common in wear. In order to study\nthe influencing factors of mechanical damage, based on the three-body abrasive\nwear, this paper discusses the wear of the secondary cutting abrasive.\nFirstly, the secondary wear model of the hemispherical abrasive grain on the\nfriction pair surface is established. Secondly, the simulation experiment is\ncarried out on the secondary scratching of the abrasive wear on the surface of\nthe part. Next, the equivalent strain data and the equivalent stress data obtained\nby the experiment are subjected to secondary friction analysis. The final\nresults show that the secondary friction damage of the hemispherical abrasive\ngrain is greater than one wear.
