ABSTRACT: 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.
