Discrete element simulation study on the friction and wear between matrix of diamond saw blade and marble

A discrete element model of friction and wear between diamond saw blade matrix and marble is established.The parameters of the matrix model are verified by indentation test, and the dynamic variation law of abrasion loss is simulated under different loads in the course of wear between the matrix and the marble.The results show that the abrasion loss of matrix increases as loads increase, then gradually stabilizes, and that the wear rate increases first and then decreases.The simulation of discrete element is in better agreement with the experimental results, which proves that the discrete element simulation method is feasible for simulating wear.
