Effect of Wheel Material on Rolling Friction and Wear Behaviors of Wheel/Rail Rollers

摘要

摘要: 为了使轮轨材料更好地匹配,降低轮轨磨损与损伤,利用MMS-2A滚动磨损试验机,研究了3种不同含碳量车轮材料与U71Mn热轧钢轨干态对磨时滚动摩擦磨损与损伤性能.结果表明:车轮材料变化基本不影响轮轨滚动摩擦因数,其摩擦因数保持在0.4左右;随车轮材料碳含量增加,车轮磨损量呈线性下降趋势,钢轨磨损量呈线性增加趋势,总轮轨磨损量呈降低趋势;不同车轮材料与U71Mn热轧钢轨对磨时的磨痕表面形貌具有较大差异,当碳含量为0.57时,车轮损伤以剥落损伤为主,试样塑性变形相对轻微,随车轮硬度降低(碳含量为0.51),表面剥落损伤轻微,但塑性变形严重;对磨钢轨试样以粘着和剥落磨损为主.

Abstract: In order to find a desired match and alleviate the wear and damage between wheel and rail materials, the rolling friction, wear, and damage behaviors between three kinds of wheel materials and U71Mn rail were investigated under dry conditions using the MMS-2A testing apparatus. The results indicate that the wheel material has no obvious effect on the rolling friction coefficient of wheel/rail, and the steady value of friction coefficient is about 0.4. With the increase of carbon content of wheel material, the wear volume of wheel specimen has a linear drop, while the wear volume of rail specimen has a linear increase; consequently the total wear volume of wheel/rail presents a decrease trend. In addition, the surface damage and morphologies of wheel specimens are obviously different for different wheel materials. When the carbon content of the wheel material is 0.57, the spalling damage is serious and the plastic deformation is slight. With the hardness of wheel specimens decreasing (carbon content 0.51), the spalling damage of wheel specimens becomes slight; however, the plastic deformation of wheel specimens is serious. For rail specimens, adhesion and spalling wear dominates the rolling wear process.
