在工程应用的很多摩擦对偶中，往往有一方是锐形的，因此，研究锐形滑块的滚动与滑动具有重要的实用意义。以锐缘硬质轮在挤压铝和软钢两种平面试样表面的滚动和滑动为研究对象，考察了两种摩擦过程中材料的受力状况和变形状况，结果表明，要在同种金属试样表面造成相同宽度的槽痕，滚动法所需要的垂直负荷比滑动法所需要的大，然而滚动法所需要的切向牵引力却比滑动法所需要的小．对两种摩擦过程中界面上的应力与材料的强度性能之关系的分析讨论指出，滚动试验中接触界面上的正应力相应于变形材料的屈服应力，因而滚动试验可以作为材料硬度的一种测量方法；滑动试验中接触界面上的剪应力相应于变形材料的流动剪应力；但滚动试验中界面剪应力与材料的流动剪应力之间，以及滑动试验中界面正应力与材料的屈服应力之间却都没有直线关系．
Of the many friction pairs used in engineering, one side is often sharp, so it is of great practical significance to study the rolling and sliding of sharp sliders. Taking the rolling and sliding of the sharp-edged rigid wheel on the surface of two flat samples of extruded aluminum and mild steel as the research object, the force conditions and deformation conditions of the two kinds of frictional processes were investigated. The results show that, The same width groove marks are created on the surface of the metal specimen. The vertical load required for the rolling method is greater than that required for the sliding method. However, the tangential traction force required for the rolling method is smaller than that required for the sliding method. The analysis and discussion of the relationship between the stress on the interface and the strength performance of the two kinds of friction process shows that the normal stress on the contact interface in the rolling test corresponds to the yield stress of the deformed material and thus the rolling test can be used as a measure of the material hardness Method; the shear stress at the contact interface of the sliding test corresponds to the flow shear stress of the deformable material; however, between the interfacial shear stress of the rolling test and the flow shear stress of the material, and between the interfacial normal stress of the sliding test and the yield stress of the material But there is no linear relationship.
