中文摘要：

建立圆锯片胎体与大理石摩擦磨损的离散元模型,并通过压痕试验验证胎体模型的模型参数,模拟并观察不同载荷下胎体与大理石磨损过程中的磨损量的动态变化规律。结果表明：随着载荷增加,胎体的磨损量不断增加,然后逐渐趋于平稳,磨损率呈先增加后下降的趋势。离散元模拟与试验结果具有较好的一致性,验证了离散元法模拟磨损是可行的。

英文摘要：

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.
