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