Stochastic simulation to the effect of abrasive parameter on two-body abrasive wear

Several existing models of two-body abrasive wear are 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.
