“…Numerical simulation methods can discretize the complex dynamic process, it is convenient for further study of friction and wear mechanism. The common numerical simulation methods are finite element method (FEM) (Cotter, 2023;Yang et al, 2022), discrete element method (DEM) (Galashev and Abramova, 2023;Liang et al, 2023), molecular dynamics (MD) method (Cui et al, 2023;Kim et al, 2023), etc. Since the copper-based graphite composites prepared by powder metallurgy are composed of particle systems, the DEM is more suitable to simulate the composite friction process, and the DEM has been successfully used to simulate complex friction and wear processes (Xie et al, 2019;Chen et al, 2022).…”

To analyze self-lubricating mechanism of copper-based graphite composites, the discrete element method (DEM) was used to study motion law of graphite particles of copper-based graphite composite/45 steel during friction. The research results show the film-forming particle layer was formed on the composite surface after a period of friction, which maintained dynamic balance depends on continuous supply of graphite in the composite. At different position, the trajectory of graphite particles is different, but the motion tendency of the graphite is the same, that is, the graphite x movement direction is consistent with the sliding direction of 45 steel, the graphite y movement direction is from the inside of the composite to the friction interface, and the motion displacement in y direction is greater than that in x direction. The load and sliding speed have an important influence on the motion law of graphite. Load or speed change the trajectory of graphite particles. However, the load and speed did not change the movement trend of graphite particles, which were consistent with motion trend at different position.
