设计了一种新型的滚动摩擦试验机，研究了润滑剂在接触区入口处的平均速度和变形过程中的相对滑动速度对摩擦性能的影响。本文介绍了摩擦计的工作原理和工件的变形模式，特别是考虑了摩擦与体积变形之间的关系。用表面粗糙的低碳钢板进行的实验表明，摩擦辊的速度比牵引辊的速度小，摩擦辊上的摩擦应力主要受摩擦辊侧的润滑条件控制。接触压力主要由牵引辊侧的摩擦条件决定。还揭示了，随着工件厚度的减少量的增加，当摩擦辊旋转时，摩擦辊侧上的摩擦应力保持恒定。当摩擦辊在工件厚度减小一定程度后停止时，摩擦应力增加。
A new rolling-type tribometer has been devised to investigate the effects on friction behavior of the average velocity of the lubricant at the inlet to the contact zone and the relative sliding velocity during deformation independently. This paper shows the principle of operation of the tribometer and deformation mode of the workpiece, especially considering the relationship between friction and bulk deformation. Experiments using mild steel strips with a dull surface showed that the friction stress on the friction roll, which has a smaller velocity than that of the traction roll, is mainly controlled by lubricating conditions on the friction roll side. The contact pressure is mainly decided by the friction conditions on the traction roll side. It was also revealed that, with an increase of the reduction in the workpiece thickness, the friction stress on the friction roll side remains constant when the friction roll is rotated. The friction stress increases when the friction roll is stopped after a certain reduction in the workpiece thickness.
