磨料尺寸对磨料磨损过程影响的随机模拟

将Monte Carlo方法与数值模拟相结合，提出了一个新的三维仿真模型，运用Monte Carlo方法随机选取磨粒的形状参数，采用打靶法生成随机的磨粒面，采用网格剖分法记忆被磨面的外形，为脊的处理以及磨损量的计算提供了一种新的方法，三三维空间内模拟了多个闰同时参与磨损的随机动态磨损过程，将模拟结果与碳钢系列材料的试验结果以及其他研究者的模拟结果进行了比较，验证了模型的有效性，系统地讨论了磨粒的粒度，尖税度和圆锥度对磨损率的影响，结果表明，粒度，尖锐度和圆锥度相互影响，共同决定了磨粒的尺寸效应。

Stochastic Simulation to the Effect of Abrasive Parameter on Two-Body Abrasive Wear

Several existing models of two-body abrasive wear have been surveyed .Through the combination of Monte Carlo method and numerical simulation approach, a new 3-D simulated model is proposed.In this model,abrasive wear parameters are determined by Monte Carlo method,and through an aiming method a random abrasive particle surface is formed.The abraded surface is remembered by dissecting,which provides a new way of treating with aside ridge and the calculation of abrasive rate.The simulation and experiment results of carbon steels are in good agreement,which ensures the validity of the model.The effects of grit size,tip radius,distributing density,furrow and aside ridge have been investigated systematically under multiple contact conditions. It can be concluded that the abrasive dimensional effect is commonly determined by grit sizes,tip radius and conical degrees.
