Analysis and Prediction of Wear Performance of Different Topography Surface

Abstract

Surface roughness parameters are an important factor affecting surface wear resistance, but the relevance between the wear resistance and the surface roughness parameters has not been well studied. This paper based on the finite element simulation technology, through the grey incidence analysis (GIA) method to quantitatively study the relevance between the wear amount of per unit sliding distance (Δ<i>V_s</i>) and the surface texture roughness parameters under dry friction conditions of the different surface topography. A zeroth order six-variables grey model, GM(0,6), for prediction the wear characteristic parameter Δ<i>V_s</i> was established, and the experiment results verified that the prediction model was accurate and reasonable.
